If A and B are independent events with P(A) = 0.3 and P(A∪B) = 0.6, then P(B) is: A. 3/7 B. 0.3 C. 0.4 D. 1/3 Answer: A) 3/7 Explanation: P(A∪B) = P(A) + P(B) − P(A)P(B). So, 0.6 = 0.3 + P(B) − 0.3P(B) → 0.3 = 0.7P(B) → P(B) = 3/7.

If A and B are independent events with P(A) = 0.3 and P(A∪B) = 0.6, then P(B) is:

Answer: A) 3/7

Explanation: P(A∪B) = P(A) + P(B) − P(A)P(B). So, 0.6 = 0.3 + P(B) − 0.3P(B) → 0.3 = 0.7P(B) → P(B) = 3/7.
