Probability Vocab and Complementary Probability

Front

What is Experimental Probability?

Back

Experimental Probability is based on relative frequency, or what actually occurs during a probability experiment.

Front

What is Theoretical Probability?

Back

Theoretical Probability is based on uniform probability, or what should occur during a probability experiment.

Front

What are Complementary Events?

Back

Complementary Events are pairs of events where the sum of their probabilities is 1.

Front

What is the Complement of an Event?

Back

The Complement of an Event is the probability of the event NOT occurring.

Front

If the probability of an event A is 0.3, what is the probability of its complementary event?

Back

0.7

Front

What is a Sample Space?

Back

A Sample Space is the set of all possible outcomes of a probability experiment.

Front

What are Independent Events?

Back

Independent Events are events where the occurrence of one event does not affect the occurrence of another.

Front

What is the formula for finding the probability of complementary events?

Back

P(A') = 1 - P(A), where P(A') is the probability of the complement of event A.

Front

What is a Simple Event?

Back

A Simple Event is an event that consists of a single outcome.

Front

What is the sum of the probabilities of all possible outcomes in a sample space?

Back

The sum of the probabilities of all possible outcomes in a sample space is 1.
