If you roll a die twice, what is the probability of rolling a 3 both times?

The probability is 1/36, calculated as (1/6) * (1/6).

Front

What is the formula for calculating the probability of dependent events?

Back

P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given A has occurred.
