Question

8. Find PLA) IFA-
(1.2.3.4) B = {3,4,5,6)
10. IU (1,2,3,4,5,6), A (23)
.
5,6,7,3) Find AUC
and B- 3,4,5) Find (AUB).​

Answer 1

Answer:

Given, universal set, U={1,2,3,4,5,6,7}

A={1,2,5,7}

B={3,4,5,6}

(A∪B)

′

=U−(A∪B)

={1,2,3,4,5,6,7}−{1,2,3,4,5,6,7}

=ϕ

A

′

∩B

′

=(U−A)n(U−B)

={3,4,6}n{1,2,7}

=ϕ

Hence (A∪B)

′

=A

′

∩B

′

.
