Question

Step by step explanation ​

Answer 1

Step-by-step explanation:

A = { 1,2,3,4,5 }

B = { 2,5,6,7,9 }

n(A)=5 n(B)=5

n(A intersection B)=2

n( A union B)=8

L.H.S. = n( A U B ) + n ( A intersection B) = 8 + 2 = 10

R.H.S. = n( A ) + n( B ) = 5 + 5 = 10

As L.H.S. = R.H.S.

Hence verified
