Unit 14 Probability Mixed Practice

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 and 1.

Front

Define independent events in probability.

Back

Independent events are two or more events where the occurrence of one event does not affect the occurrence of the other.

Front

What is the formula for the probability of two independent events A and B occurring together?

Back

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

Front

What does it mean for events to be mutually exclusive?

Back

Mutually exclusive events cannot occur at the same time; the occurrence of one event means the other cannot occur.

Front

How do you calculate the probability of either event A or event B occurring?

Back

For mutually exclusive events, P(A or B) = P(A) + P(B). For non-mutually exclusive events, P(A or B) = P(A) + P(B) - P(A and B).

Front

What is the probability of selecting a female AND she has to like Jeeps?

Back

This is calculated using the formula for the intersection of two events.

Front

If P(A) = 0.4 and P(B) = 0.5, what is P(A and B) if A and B are independent?

Back

P(A and B) = P(A) * P(B) = 0.4 * 0.5 = 0.2.

Front

What is the probability of an event that is certain to happen?

Back

The probability of an event that is certain to happen is 1.

Front

What is the probability of an event that is impossible?

Back

The probability of an event that is impossible is 0.

Front

How do you express probability as a fraction?

Back

Probability can be expressed as a fraction of the number of favorable outcomes over the total number of possible outcomes.
