# Probability

From The School of Biomedical Sciences Wiki

Probability is the likelihood or measure of a specific event taking place ^{[1]}.

Usually represented as a percentage, probability is always a number smaller that 0, where a value of 1 represents definite certainty of a even, meanwhile 0 represents an impossible event.

Probabilities of multiple numbers of events all happening at once can be worked out given 2 criteria:

- You have the probability of each event taking place
- The events are not mutually exclusive ( can happen at the same time)

Probabilities of events that are non-mutually exclusive can be worked out through multiplying the probability of each individual event together.

For example the probability of rolling two 6’s on a set of dice is 1/36. This Is worked out because the probability of rolling a 6 is 1/6 as there are 6 sides, and (1/6)*(1/6)=1/36.
