Analyze the diagram below and complete the instructions that follow.


Find |P|

A. 8

B. 15

C. 22

D. 24

Answer 1

|P|=24

Explanation:

The notation |P| stays for the cardinality of the set, i.e. the number of elements in the set P.

From the diagram we can see that 15 elements belong only to set P and do not belong to the set Q. 9 elements belong to both sets Q and P.

Thus, 15 + 9 =24 elements belong to the set P.

Hence, |P|=24.
