What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 (impossible event) and 1 (certain event).

Front

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 at all, with a probability of 0.

Front

How do you calculate the probability of an event?

Back

Probability is calculated using the formula: Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is a favorable outcome in probability?

Back

A favorable outcome is an outcome that is counted in the event for which we are calculating the probability.

What is the total number of outcomes in a probability experiment?

Back

The total number of outcomes is the complete set of all possible results of the experiment.
