Question

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

Answer 1

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!!!
