Question

n(A)=35 n(B)=37 n(AUB)=60 Find n(AnB)​

Answer 1

Answer:

N(U)= 60

N(AUB)'=10

N(AUB)=N(U)- N(AUB)'

= 60-10

=50

So N(A intersection B)= N(A)+N(B) - N (AUB)

= 35+24-50

=9

Step-by-step explanation:

Answer 2

Answer:

12

Step-by-step explanation:

we know that

n(AUB) = n(A) + n(B) - n(AnB)

this implies that

60 = 35 + 37 - n(AnB)

n(AnB) = 72 - 60

n(AnB) = 12
