How do you calculate the probability of two independent events occurring together?

• Add the probabilities of each event: P(A and B) = P(A) + P(B).

• Multiply the probabilities of each event: P(A and B) = P(A) * P(B).

• Subtract the probabilities of each event: P(A and B) = P(A) - P(B).

• Divide the probabilities of each event: P(A and B) = P(A) / P(B).
