Let the events A and B with P (A ∪ B) = 1/2, P (A ∩ B) = 1/12, P (complement of A) = 2/3?
Let the events A and B with
P (A ∪ B) = 1/2, P (A ∩ B) = 1/12, P (complement of A) = 2/3
Calculated: P (A) P (B), P(A-B), P(B-A) and P( complement of B)

P(A')=2/3
P(A)=1-2/3=1/3
P(AUB)=P(A)+P(B)-P(AnB)
1/2=1/3+P(B)-1/12
P(B)=1/12
P(B')=11/12
