Question

0.8) If A and B are two subsets of the universal set X and n(X)=50, n(A)=35, n(B)=20, n(AUB)= 45 then find
(a) CAN B) (b) n(A'n B)​

Answer 1

Answer:

a number is the answer of this question

Answer 2

Answer:

n(A∩B=10

n(A'∩B)=10

Step-by-step explanation:

I assume that your question is :

Find(a) n (A∩B) (b) n( A'∩B)

n(X)=50, n(A)=35, n(B)=20, n(AUB)= 45

(a) We know that

n(A∩B)=n(A) +n(B)-n(AUB)

=35+20-45

=10

Now n(A'∩B)=n(B)-n(A∩B)

=20-10=10
