What is Meant by Probability?

In mathematics and statistics, Probability is used to measure the likelihood of an event that is going to occur. The probability is a number that always lies between 0 and 1. If the probability value is equal to 1, then something will always happen. If the probability value is equal to 0, then something will never happen. It is noted that the probability of all the events in the sample space always adds up to 1. The formula to calculate the probability of an event is given by
