It is expressed as a number between 0 and 1 (where 0 shows false and 1 shows true). The Probability Web is a collection of probability resources on the World Wide Web (WWW). Since the two outcomes 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". Probability is the chance that given event will occur. Often, we want to compute the probability of an event from the known probabilities of other events. Probability is the chance that something will happen - how likely it is that some event will happen. The study of probability helps us figure out the likelihood of something happening . A simple example is the toss of a fair (unbiased) coin. Using combinatorics to solve questions in probability.
