Number of X is randomly selected from the set of odd numbers and Y is ...
Set A = {1 ,2 ,3 ,4 ,5 ,6 ,7 } and z =x + y
x = set of odd numbers
y = set of even numbers
Z = product of two prime numbers
Z = x + y = 7 + 6 = 13
n(E4)=3
x = set of odd numbers
y = set of even numbers
Z = product of two prime numbers
Z = x + y = 7 + 6 = 13
n(E4)=3

Number of X is randomly selected from the set of odd numbers and Y is ...
There are a few key points to consider in order to solve this problem:
1. Understanding the given sets: We are given two sets - the set of odd numbers {1, 3, 5, 7} and the set of even numbers {2, 4, 6}.
2. Selecting the numbers: We need to randomly select one number from each set. Let's consider the possible combinations:
- (1, 2)
- (1, 4)
- (1, 6)
- (3, 2)
- (3, 4)
- (3, 6)
- (5, 2)
- (5, 4)
- (5, 6)
- (7, 2)
- (7, 4)
- (7, 6)
3. Calculating the product: For each combination, we need to calculate the product of the two numbers. Let's calculate them:
- (1, 2) -> Z = 1 * 2 = 2
- (1, 4) -> Z = 1 * 4 = 4
- (1, 6) -> Z = 1 * 6 = 6
- (3, 2) -> Z = 3 * 2 = 6
- (3, 4) -> Z = 3 * 4 = 12
- (3, 6) -> Z = 3 * 6 = 18
- (5, 2) -> Z = 5 * 2 = 10
- (5, 4) -> Z = 5 * 4 = 20
- (5, 6) -> Z = 5 * 6 = 30
- (7, 2) -> Z = 7 * 2 = 14
- (7, 4) -> Z = 7 * 4 = 28
- (7, 6) -> Z = 7 * 6 = 42
4. Identifying the product of two prime numbers: From the calculated products, we can see that the following products are the product of two prime numbers:
- 2 (2 is a prime number)
- 3 (3 is a prime number)
- 5 (5 is a prime number)
- 7 (7 is a prime number)
- 11 (11 is a prime number)
- 13 (13 is a prime number)
- 17 (17 is a prime number)
- 19 (19 is a prime number)
- 23 (23 is a prime number)
- 29 (29 is a prime number)
- 31 (31 is a prime number)
5. Calculating the probability: Out of the total 12 possible combinations, there are 11 combinations where Z is the product of two prime numbers. Therefore, the probability of Z being the product of two prime numbers is 11/12, which is equal to 1/4.
Hence, the correct answer is option C) 1/4.
1. Understanding the given sets: We are given two sets - the set of odd numbers {1, 3, 5, 7} and the set of even numbers {2, 4, 6}.
2. Selecting the numbers: We need to randomly select one number from each set. Let's consider the possible combinations:
- (1, 2)
- (1, 4)
- (1, 6)
- (3, 2)
- (3, 4)
- (3, 6)
- (5, 2)
- (5, 4)
- (5, 6)
- (7, 2)
- (7, 4)
- (7, 6)
3. Calculating the product: For each combination, we need to calculate the product of the two numbers. Let's calculate them:
- (1, 2) -> Z = 1 * 2 = 2
- (1, 4) -> Z = 1 * 4 = 4

- (3, 2) -> Z = 3 * 2 = 6
- (3, 4) -> Z = 3 * 4 = 12
- (3, 6) -> Z = 3 * 6 = 18
- (5, 2) -> Z = 5 * 2 = 10
- (5, 4) -> Z = 5 * 4 = 20
- (5, 6) -> Z = 5 * 6 = 30
- (7, 2) -> Z = 7 * 2 = 14
- (7, 4) -> Z = 7 * 4 = 28
- (7, 6) -> Z = 7 * 6 = 42
4. Identifying the product of two prime numbers: From the calculated products, we can see that the following products are the product of two prime numbers:
- 2 (2 is a prime number)
- 3 (3 is a prime number)
- 5 (5 is a prime number)
- 7 (7 is a prime number)
- 11 (11 is a prime number)
- 13 (13 is a prime number)
- 17 (17 is a prime number)
- 19 (19 is a prime number)
- 23 (23 is a prime number)
- 29 (29 is a prime number)
- 31 (31 is a prime number)
5. Calculating the probability: Out of the total 12 possible combinations, there are 11 combinations where Z is the product of two prime numbers. Therefore, the probability of Z being the product of two prime numbers is 11/12, which is equal to 1/4.
Hence, the correct answer is option C) 1/4.
