How do you calculate the probability of two dependent events occurring?

Back

To calculate the probability of two dependent events A and B occurring, use the formula: P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given that A has occurred.

Front

What is the formula for conditional probability?

Back

The formula for conditional probability is P(A|B) = P(A and B) / P(B), where P(A|B) is the probability of A given B.

What is the combined probability of picking a dark chocolate both times?

Back

The combined probability is P(Dark 1st) * P(Dark 2nd|Dark 1st) = (10/17) * (9/16) = 90/272 = 5/17.
