Represent the union of two sets by Venn diagram for each of the following.

A = {3, 4, 5, 7}

_{B = {1, 4, 8}}

If n(A) = 20, n(B) = 28 and n (A ∪ B) = 36 then n (A ∩ B) = ?

In a class, 8 students out of 28 have a dog as their pet animal at home, 6 students have a cat as their pet animal. 10 students have dog and cat both, then how many students do not have a dog or cat as their pet animal at home?
