# Probability For Single Event Calculator

Probability is the measurement of the likeliness that an event will occurs.The higher the probability of an event, the more certain we are that the event will occur.We can take an example of simple toss of a unbiased coin. Since there are two favourable outcomes which are equally probable, the probability of "heads" equals the probability of "tails", so the probability is 1/2 (or 50%) chance of either "heads" or "tails". This Calculator Allows You to get the accurate probability of a single event.

**Single Event Probability Formula:**

Probability of event A that occurs P(A)= n(A) / n(S)

Probability of event A that does not occur P(A')= 1 - P(A)
