The probability of an event a is the number of ways event a can occur divided by the total number of possible outcomes the probability of an event a, symbolized by p(a), is a number between 0 and 1, inclusive, that measures the likelihood of an event in the following way. Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions in common usage, the word probability is used to mean the chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100.

Use these examples of probability to guide you through calculating the probability of simple events probability is the chance or likelihood that an event will happen it is the ratio of the number of ways an event can occur to the number of possible outcomes.
