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 an Outcome in probability?

Back

An Outcome is the result of an event.

Front

What is the probability of the complement of an event?

Back

The probability of the complement of an event is calculated as 1 minus the probability of the event occurring.

Front

What is the complement of drawing a red marble if the probability of drawing a red marble is 0.5?

Back

The complement is 0.5.

Front

What are complementary events in probability?

Back

Complementary events are two events that are mutually exclusive and together cover all possible outcomes.

Front

What is Theoretical Probability?

Back

Theoretical Probability is based on the possible outcomes in a probability experiment, assuming all outcomes are equally likely.

Front

What is Sample Space?

Back

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

Front

If the probability of spinning on black is 1/8, what is the probability of the complement?

Back

The probability of the complement is 7/8.

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one event does not affect the occurrence of the other.

Front

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

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.
