Question

U={1,2,3,4,5,6,7,9},A={2,3,6},B={3,5,7}„A'nB=?​

Answer 1

Answer:

{5,7}

Step-by-step explanation:

A'= u-A = {1,4,5,7,9}

now A'intersection B = common in A'and B

= {5,7}

Answer 2

Answer:

U={1, 2,3,4,5,6,7,8,9}

A={2, 4,6,8}

B={2,3,5}

Step-by-step explanation:

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

B={1,4,6,8,9}

so( A, N, B) =(1,9)

(AUB) '=U-(AUB)

(AUM) '= {1,2,3,4,5,6,7,8,9} -{ 2,3,4,5,6,7}

(AUB) '={1,9}=(ANB)
