Theoretical Probability

A given event's probability of happening shows mathematically (numerically) how likely it is to occur. If an event has a probability of 1, it will always occur, whereas it will never occur if its probability is 0. Classical problems of probability usually require you to compare the likelihoods of two related things happening, as well as how the occurrence of one event can influence the likelihood that other events happen in the future. When we consider all possible events, according to the formula:

Probability = Number of favorable events / Number of possible events
