Mathematics for IGCSE & O level - Probability (Section 3 - No. 23)
If event A and event B are independent, which formula correctly calculates the probability of both events happening?
P(A or B) = P(A) + P(B)
P(A and B) = P(A) + P(B)
P(A and B) = P(A) * P(B)
P(A or B) = P(A) * P(B)
Maelezo
For independent events, you multiply the probabilities of each event to get the probability of both events happening.
