What is the formula for calculating the probability of two independent events occurring together?

Back

P(A and B) = P(A) * P(B), where P(A) is the probability of event A and P(B) is the probability of event B.

What is the probability of rolling a number greater than 2 on a standard die?

Back

The probability is 4/6 or 2/3, since the numbers greater than 2 are 3, 4, 5, and 6.

What is the combined probability of rolling an even number (2, 4, 6) and spinning green on a spinner with 4 equal sections?

Back

The combined probability is 3/24 or 1/8, since there are 3 even numbers and 1 green section.
