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

Back

To find the probability of two independent events A and B occurring together, multiply their individual probabilities: P(A and B) = P(A) × P(B).

How does picking a red marble first affect the probability of picking a green marble second?

Back

It makes it less likely because there are fewer total marbles left.

Front

What is the formula for calculating the probability of an event?

Back

The formula is P(Event) = Number of favorable outcomes / Total number of outcomes.

What is an independent event in probability?

Back

An independent event is an event whose outcome does not affect the outcome of another event.
