N(E) = 40 , n(A) = 23 , n(B') = 28 Find n(A U )

1.	N(E) = 40 , n(A) = 23 , n(B') = 28 Find n(A U )
Answer» ANSWER: *N(U)= 60* *N(U)= 60N(AUB)'=10* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'= 60-10* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'= 60-10=50* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'= 60-10=50So N(A INTERSECTION B)= N(A)+N(B) - N (AUB)* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'= 60-10=50So N(A intersection B)= N(A)+N(B) - N (AUB)= 35+24-50* *N(U)= 60N(AUB)'=10N(AUB)=N(U)- N(AUB)'= 60-10=50So N(A intersection B)= N(A)+N(B) - N (AUB)= 35+24-50=9...... hope* it *will* *HELP* *you* *mam*!!!
