The probability of an event occurring can be found by dividing the number of possibilities of the event successfully occurring by the total amount of events possible. Probability can be expressed as a decimal but is more commonly expressed in a percentage, which is obta...

Theoretically, define the probability of a specific outcome of any event as the ratio of the number of outcomes that favor that specific outcome to the total number of possible outcomes of that event. Mathematically, define the probability of outcome "A" with this equat...

Mathigon notes that studying probability is necessary in order to better understand the likelihood of a particular thing happening. An individual is able to better calculate such likelihoods if he has more information and context about the subject he is attempting to pr...

Probabilities may be marginal, joint or conditional. A marginal probability is the probability of a single event happening. It is not conditional on any other event occurring.

Different types of probability include conditional probability, Markov chains probability and standard probability. Standard probability is equal to the number of wanted outcomes divided by the number of possible outcomes.

The theoretical definition of probability states that if the outcomes of an event are mutually exclusive and equally likely to happen, then the probability of the outcome "A" is: P(A) = Number of outcomes that favors A / Total number of outcomes. For example, there are ...

The different ways in which probability is used in real life include making odds of winning a major lottery game, weather forecasting, having coin tosses in sports and the playing of board games. Permutations and combinations are important in games of chance, such as st...
