(a) If no evidence is observed, are Burglary and Earthquake independent?Proving it from the numerical semantics and from the topological semantics-As per Figure 14.2 given in the question, the following information can be obtained:

P(Burglary) = 0.001, P(¬Burglary) = 0.999, P(Earthquake) = 0.002, P(¬Earthquake) = 0.998, P(Alarm|Burglary, Earthquake)P(¬Alarm|Burglary, Earthquake)Observation:The given Bayesian network can be expressed by using joint probabilities:$$P(Burglary, Earthquake, Alarm, JohnCalls, MaryCalls)$$$$=P(MaryCalls|Alarm)P(JohnCalls|Alarm)P(Alarm|Burglary, Earthquake)P(Burglary)P(Earthquake)$$To prove the independence between burglary and earthquake, the following condition must be satisfied:

P(Burglary ∩ Earthquake) = P(Burglary) × P(Earthquake)According to the information given in the question,P(Burglary ∩ Earthquake) = P(Burglary) × P(Earthquake) × P(Alarm|Burglary, Earthquake) × P(¬Alarm|Burglary, Earthquake) = 0.001 × 0.002 × 0.95 × 0.94 ≈ 1.29 × 10^-6P(Burglary) = 0.001Therefore, P(Burglary) × P(Earthquake) = 0.001 × 0.002 = 2 × 10^-6As P(Burglary ∩ Earthquake) ≠ P(Burglary) × P(Earthquake), burglary and earthquake are not independent from each other when no evidence is observed.

To prove whether Burglary and Earthquake are independent given Alarm = true, we need to check whether the following condition is true or not:

P(Burglary|Alarm) = P(Burglary) or P(Burglary|Alarm, Earthquake) = P(Burglary|Alarm)As per the question, we have:P(Burglary|Alarm = true) and P(Burglary|Alarm = true,

Earthquake)P(Burglary|Alarm = true) = [P(Burglary ∩ Earthquake ∩ Alarm) + P(Burglary ∩ ¬Earthquake ∩ Alarm)] / P(Alarm = true) [from Bayes’ theorem]P(Burglary ∩ Earthquake ∩ Alarm) = P(Burglary) × P(Earthquake) × P(Alarm|Burglary,

Earthquake) = 0.001 × 0.002 × 0.95 ≈ 1.29 × 10^-6P(Burglary ∩ ¬Earthquake ∩ Alarm) = P(Burglary) × P(¬Earthquake) × P(Alarm|Burglary,

¬Earthquake) = 0.001 × 0.998 × 0.94 ≈ 0.0009381P(Alarm = true) = P(Burglary ∩ Earthquake ∩ Alarm) + P(Burglary ∩ ¬Earthquake ∩ Alarm) + P(¬Burglary ∩ Earthquake ∩ Alarm) + P(¬Burglary ∩ ¬Earthquake ∩ Alarm) = 0.000998 × 0.95 + 0.0009381 + 0.000002 × 0.29 + 0.998 × 0.001 × 0.71 = 0.001973P(Burglary|Alarm = true) = [P(Burglary ∩ Earthquake ∩ Alarm) + P(Burglary ∩ ¬Earthquake ∩ Alarm)] / P(Alarm = true) = [1.29 × 10^-6 + 0.0009381] / 0.001973 ≈ 0.475P(Burglary|Alarm = true,

Earthquake) = P(Burglary|Alarm = true, Earthquake) = P(Burglary ∩ Alarm ∩ Earthquake) / P(Alarm = true, Earthquake) [from Bayes’ theorem]P(Burglary ∩ Alarm ∩ Earthquake) = P(Burglary) × P(Earthquake) × P(Alarm|Burglary,

Earthquake) = 0.001 × 0.002 × 0.95 ≈ 1.29 × 10^-6P(Alarm = true, Earthquake) = P(Burglary ∩ Earthquake ∩ Alarm) + P(¬Burglary ∩ Earthquake ∩ Alarm) = 0.001998 × 0.95 + 0.002 × 0.29 = 0.0019681P(Burglary|Alarm = true, Earthquake) = P(Burglary ∩ Alarm ∩ Earthquake) / P(Alarm = true, Earthquake) = 1.29 × 10^-6 / 0.0019681 ≈ 6.55 × 10^-4

Therefore, P(Burglary|Alarm = true) ≠ P(Burglary|Alarm = true, Earthquake), which means Burglary and Earthquake are not independent given Alarm = true.

Steps involved:1. Load first number from memory location 2:3 into a register. 2. Load second number from memory location 5:2 into another register. 3. Multiply two numbers stored in registers. 4. Store result.

The CISC (Complex Instruction Set Computer) approach for multiplying two numbers typically involves multiple steps to perform the multiplication operation. Here are the steps involved in the CISC approach for multiplying two numbers in memory:

1. Load the first number from memory location 2:3 into a register.

2. Load the second number from memory location 5:2 into another register.

3. Multiply the two numbers stored in the registers.

4. Store the result of the multiplication back into memory location 2:3.

In the first step, the CISC approach involves loading the first number from memory into a register. This allows for faster access and manipulation of the data. Similarly, in the second step, the second number is loaded from memory into another register. Once both numbers are loaded into registers, the actual multiplication operation takes place in the third step. The CPU performs the multiplication operation on the two numbers stored in the registers using the designated multiply instruction. This step utilizes the hardware's multiplication capabilities to perform the computation.

Finally, in the fourth step, the result of the multiplication is stored back into memory. The product is stored in memory location 2:3, replacing the original value. The CISC approach for multiplication involves breaking down the operation into multiple steps to allow for more complex instructions and operations to be performed. This approach allows for more flexibility and functionality in executing complex operations, but it may also result in longer instruction execution times compared to simpler architectures like RISC (Reduced Instruction Set Computer). CISC architectures often include a wide range of instructions to support various operations, including complex arithmetic and memory manipulation.

class Customer(Person):

   def __init__(self, name, address, telephone_number, customer_number, mailing_list):

       super().__init__(name, address, telephone_number)

       self.customer_number = customer_number

# Creating an instance of the Customer class

customer1 = Customer("John Doe", "123 Main St", "555-1234", "C12345", True)

# Accessing attributes of the customer

print("Customer Name:", customer1.name)

print("Customer Address:", customer1.address)

print("Customer Telephone Number:", customer1.telephone_number)

print("Customer Number:", customer1.customer_number)

print("Wants to be on Mailing List:", customer1.mailing_list)

Explanation:

In this example, the Person class is the base class, and the Customer class is a subclass of Person. The Person class has data attributes for a person's name, address, and telephone number. The Customer class extends the Person class and adds two additional data attributes: customer_number and mailing_list.

The __init__ method is used to initialize the attributes of each class. The super().__init__() call in the Customer class ensures that the attributes from the Person class are also initialized properly.

Finally, an instance of the Customer class (customer1) is created and its attributes are accessed and printed in a simple program.

Well, a binary search has to be ordered. So ima just say linear search..

Explanation:

I think its linear..

A binary search can be done on a list that is not ordered.

Binary search is a fast technique that finds an item from a sorted list of objects with a run-time complexity of O(log n), where n is the total number of elements. Divide and conquer concepts are used in binary search.

When performing a binary search on an array in computer programming, the array must be sorted in ascending order, i.e. from the least to the highest with respect to the data value.

The primary benefit of using binary search is that it does not scan every element in the list. Instead of scanning each element, it searches the first half of the list. As a result, a binary search takes less time to find an element than a linear search.

the information gain of the attribute that divides the collection into three collections is approximately 0.266.

To calculate the information gain of an attribute, we need to quantify the reduction in entropy (uncertainty) achieved by splitting the data based on that attribute. The information gain is calculated using the formula:

Information Gain = Entropy(parent) - Weighted Sum of Entropies(children)

First, let's calculate the entropy of the parent collection, which consists of 12 positive items and 54 negative items.

Entropy(parent) = - (p_pos * log2(p_pos) + p_neg * log2(p_neg))

where p_pos is the proportion of positive items and p_neg is the proportion of negative items in the parent collection.

p_pos = 12 / (12 + 54) = 0.1818

p_neg = 54 / (12 + 54) = 0.8182

Entropy(parent) = - (0.1818 * log2(0.1818) + 0.8182 * log2(0.8182))

               ≈ 0.684

Next, let's calculate the entropies of the three children collections obtained by splitting the parent collection.

Child 1: 10 positive items and 20 negative items

Child 2: 2 positive items and 12 negative items

Child 3: 0 positive items and 22 negative items

Entropy(child1) = - (p_pos * log2(p_pos) + p_neg * log2(p_neg))

               = - ((10 / 30) * log2(10 / 30) + (20 / 30) * log2(20 / 30))

               ≈ 0.918

Entropy(child2) = - ((2 / 14) * log2(2 / 14) + (12 / 14) * log2(12 / 14))

               ≈ 0.811

Entropy(child3) = 0  (since there are no positive items)

Now, we calculate the weighted sum of entropies using the proportions of items in each child collection.

Weighted Sum of Entropies(children) = (30 / 66) * Entropy(child1) + (14 / 66) * Entropy(child2) + (22 / 66) * Entropy(child3)

Weighted Sum of Entropies(children) ≈ (0.4545 * 0.918) + (0.2121 * 0.811) + (0.3333 * 0)

                                     ≈ 0.418

Finally, we can calculate the information gain:

Information Gain = Entropy(parent) - Weighted Sum of Entropies(children)

               ≈ 0.684 - 0.418

               ≈ 0.266

Therefore, the information gain of the attribute that divides the collection into three collections is approximately 0.266.
