If P(A)=0.7, P(B)=0.6, and the maximum possible value of P(A∩B) is 0.6, then the minimum possible value of P(A∪B) is:
Correct Answer: Option A
Explanation:
P(A∪B) = P(A)+P(B)-P(A∩B). To minimize union, maximize intersection: max=0.6. So min union = 0.7+0.6-0.6=0.7.
P(A∪B) = P(A)+P(B)-P(A∩B). To minimize union, maximize intersection: max=0.6. So min union = 0.7+0.6-0.6=0.7.
