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.
