Question

4)If A
= {2,4,6} B={1,3,5,7,9} Find AuB
and
verify n (AUB) =n(A)+n(B)
​

Answer 1

Step-by-step explanation:

A = {2, 4, 6}

n(A) = 3

B = { 1, 3, 5, 7, 9}

n(B) = 5

A U B = {1, 2, 3, 4, 5, 6, 7, 9}

n(A U B) = 8

Now, n(A U B) = n(A) + n( B)

8 = 3 + 5

8 = 8

R.H.S = L.H.S

Hence, verified....
