Answer:

Union = 15

Step-by-step explanation:

Given

n(A) = 5; n(B) = 10; n(C) = 15

Solving (a): Possible union elements

This is the represented by element with the largest number of the sets

i.e.

Union = 15

Solving (b): Possible intersection elements

This is the represented by element with the least number of the sets

i.e.

Intersection = 5
