Answer:
n(AUB) = n(U) - n(AUB)’
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,n(AUB) = n(A) + n(B) - n(A∩B)
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,n(AUB) = n(A) + n(B) - n(A∩B)so,
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,n(AUB) = n(A) + n(B) - n(A∩B)so,n(A∩B) = n(A) + n(B) - n(AUB)
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,n(AUB) = n(A) + n(B) - n(A∩B)so,n(A∩B) = n(A) + n(B) - n(AUB)= 35 + 24 - 50
n(AUB) = n(U) - n(AUB)’n(AUB) = 60 - 10= 50Now,n(AUB) = n(A) + n(B) - n(A∩B)so,n(A∩B) = n(A) + n(B) - n(AUB)= 35 + 24 - 50= 9 is your answer…..
