Question

prove that if a and b are two sets then (AUB)'U(A'nB) is A'

Answer 1

Answer:

Step-by-step explanation:

(A union b )’ = universal set except a union b

(a’ intersection b) = only setb - a intersection b

so it includes only a’

Answer 2

Answer:

Step-by-step explanation:(AUB)'=(A∩B)

                                           (A'∩B)=B

                                           ∴(A∩B)UB=A'
