Mathematics for IGCSE & O level - Probability (Section 8 - No. 47)
If the probability of event A is 0.3 and the probability of event B is 0.4, what is the probability of both events happening if the events are independent?
0.12
0.7
0.3
0.4
解释
For independent events, the probability of both happening is calculated by multiplying individual probabilities (0.3 * 0.4 = 0.12).
