Probability - Multiplication Rule

Front

What is the Multiplication Rule in probability?

Back

The Multiplication Rule states that the probability of two independent events occurring together is the product of their individual probabilities. If A and B are independent events, then P(A and B) = P(A) * P(B).

How do you calculate the probability of independent events?

Back

To calculate the probability of independent events, multiply the probability of the first event by the probability of the second event. For example, if P(A) = 1/4 and P(B) = 1/2, then P(A and B) = (1/4) * (1/2) = 1/8.

How do you find the probability of multiple independent events occurring in sequence?

Back

Multiply the probabilities of each individual event. For example, if P(A) = 1/3 and P(B) = 1/4, then P(A and B) = (1/3) * (1/4) = 1/12.

What is the total number of outcomes when rolling two dice?

Back

The total number of outcomes when rolling two dice is 36, as each die has 6 faces, so 6 * 6 = 36.

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

Back

The formula for calculating the probability of an event is P(E) = Number of favorable outcomes / Total number of outcomes.
