### What does probability mean?

Probability in mathematics and statistics is used to determine the probability of an event occurring. Probability is always a number between 0 to 1. If the probability value equals 1, something always happens. If the probability is 0, nothing will ever happen. The probability of the events within the sample space is always 1. The formula for calculating the probability of an occurrence is

Probability of an event P(E), is the number of favorable outcomes divided by the total number of outcomes.
