If P = {1, 2, 3, 5, 7}, Q = {1, 3, 6, 10, 15}, Universal Set S = {1, 2...
Given:
P = {1, 2, 3, 5, 7}
Q = {1, 3, 6, 10, 15}
Universal Set S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

To find:
The cardinal number of P U Q.

Solution:
Cardinal number is the number of elements in a set.

To find the cardinal number of P U Q, we need to find the elements present in P U Q.

P U Q represents the set of all elements that are either in P or in Q or in both.

Therefore, P U Q = {1, 2, 3, 5, 7, 6, 10, 15}

The cardinal number of P U Q is the number of elements in the set P U Q, which is 8.

Hence, the correct answer is option (c) 8.
