Question

If A and B are two sets such that n(A) = 17, n(B) = 21 and n(A ⋃ B) = 32, then n(A ∩ B) is:

6

5

4

8​

Answer 1

Answer:

8

Step-by-step explanation:

Use the formula or solve it by Venn diagram.

I will use formula to solve it

n(A U B) = n(A) + n(B) - n(A intersection B)

32 = 17+21 - n(A intersection B)

32= 38 - n(A intersection B)

n(A intersection B) = 38-32

n(A intersection B) = 8
