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

Back

P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What does it mean if an event is 'certain'?

Back

An event is certain if it is guaranteed to happen, with a probability of 1.

Front

What does it mean if an event is 'impossible'?

Back

An event is impossible if it cannot happen, with a probability of 0.

Front

What is the probability of NOT getting a specific outcome?

Back

P(NOT Event) = 1 - P(Event).
