Probability is a branch of mathematics/ Aptitude that deals with the likelihood of certain events occurring. It is used to calculate the chance or probability of an event occurring and is often expressed as a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain to occur. The probability of an event can also be expressed as a percentage or a fraction.

In probability theory, an event is any outcome or set of outcomes of an experiment or trial. For example, in a coin toss, the event "heads" would be one outcome and the event "tails" would be the other. In a roll of a die, the event "rolling a 6" would be one outcome and the event "not rolling a 6" would be the other.

Probabilities can be calculated using various methods, such as counting, using probability formulas, or using probability distributions. Probabilities can also be conditional, meaning that the probability of an event occurring depends on the outcome of another event.
