What is probability?

Back

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

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of outcomes).

Back

Total number of outcomes.

What is a favorable outcome in probability?

Back

A favorable outcome is an outcome that is desired or counts towards the event we are calculating the probability for.

If there are 3 Orange and 2 Yellow M & M's, what is the probability of picking one of each?

Back

(3/21) * (2/20) = 6/420 = 1/70.

What is the sample space in probability?

Back

The sample space is the set of all possible outcomes of a probability experiment.
