Answer:
the number of elements are in A but not in B
n(A-B) = 75
Step-by-step explanation:
Given universal set (S) = 140
also given A and B are subsets of 'S'
Given n(A) = 76 , n(B) =16 and n(AUB) =91
we have to find n(A-B) ?
we can use formula
n(A-B) = n(AUB)-n(B)
= 91 - 16 =75
Final answer:-
the number of elements are in A but not in B
n(A-B) = 75
