Mathematics for IGCSE & O level - Probability (Section 6 - No. 45)
If the probability of Event A is 0.6 and the probability of Event B is 0.4, and the events are independent, what is the probability of A happening and B not happening?
0.24
0.36
0.40
0.16
解释
P(A and not B) = P(A) * P(not B) = 0.6 * (1-0.4) = 0.6 * 0.6 = 0.36.
