Intro to probability

What is the sample space in probability?

Back

The set of all possible outcomes of one or more events. For example, for a single die roll, the sample space is {1, 2, 3, 4, 5, 6}.

Front

What is the range of probabilities?

Back

Probabilities are always between 0 and 1, or 0% and 100%.

Front

What is the complement of an event in probability?

Back

The complement of an event is the set of outcomes in which the event does not occur. For example, if the event is selecting a jacket, the complement is not selecting a jacket.

What is an event in probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

What is a simple event?

Back

A simple event is an event that consists of a single outcome.

Front

What is a compound event?

Back

A compound event is an event that consists of two or more simple events.

Front

What is the probability of an impossible event?

Back

The probability of an impossible event is 0.
