If a spinner is spun twice, what is the probability that it lands on red first and then blue?

Back

Independent: The probability is calculated as P(red) * P(blue) = (1/2) * (1/2) = 1/4.

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

Back

P(A and B) = P(A) * P(B) for independent events.
