Step-by-step explanation:
here
total students =28
let A denote students having dog as a pet animal
then n(A)= 8
let B denote the students having cat as pet animal
then n(B)= 6
let (AUB) denote students having both cat and dog as pet animal
then n(AUB)= 10
we have to find students not having any pet
we have
n(A)+n(B)-n(AnB)= n(AUB)
=> n(AnB)= 6+8-10= 4
n(A)-n(AnB)= 8-4= 4
n(B)-n(AnB)= 6-4= 2
total number of students having no pet = 28-4-2-8-6= 28-20= 8
hope it helps ✌
