Define the Multiplication Rule in probability.

Back

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

Front

What is a mutually exclusive event?

Back

Two events are mutually exclusive if they cannot occur at the same time.

Front

How do you calculate the probability of the union of two mutually exclusive events?

Back

For mutually exclusive events A and B, the probability of A or B occurring is P(A or B) = P(A) + P(B).

Front

What is conditional probability?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred, denoted as P(A|B).
