Back

The shaded region represents the probability of the event occurring, which is not B in this case.

Front

Define probability.

Back

Theoretical probability is based on the expected outcomes, while experimental probability is based on actual experiments.

Front

What is a mutually exclusive event?

Back

Mutually exclusive events are events that cannot occur at the same time.

Front

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

Back

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

Front

What is the complement of an event?

Back

The complement of an event A is the event that A does not occur, denoted as A'.
