Probability is the measure of the likelihood of an event occurring. It is quantified as a number between 0 and 1, with 1 signifying certainty, and 0 signifying that the event cannot occur. It follows that the higher the probability of an event, the more certain it is that the event will occur. See more Given a probability A, denoted by P(A), it is simple to calculate the complement, or the probability that the event described by P(A) does not occur, P(A').

If the probability density at X = x is 0.25, then this means that the limit as h goes to 0 of P (x-h < X < x+h) / (2h) = 0.25. Loosely speaking, the probability that X is in a small interval containing x is about 0.25 times the length of that interval.

WebProbability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
