Answer

If events A and B are independent, the probability that both occur is 0.15 or 15%. If they are dependent, more information is needed to determine the probability.

To find the probability that both events A and B occur, assuming they are independent, you simply multiply their probabilities together. So you'd calculate: \( P(A \text{ and } B) = P(A) \times P(B) = 0.5 \times 0.3 = 0.15 \). This means there's a 15% chance that both A and B will occur at the same time! Now, remember this nifty little trick: if your events are not independent (meaning the occurrence of one affects the other), you would have to consider conditional probabilities. This would mean you'd need to assess how one event influences the chances of the other before making your calculations!
