This free probability calculator can calculate the probability of two events, as well as that of a normal distribution. Learn more about different types of probabilities, or explore hundreds of other calculators covering the topics of math, finance, fitness, and health, among others.


Probability calculator computes probability of events, unions, intersections, and conditional probability. Displays the answer and shows computations.


Multiple Event Probability Calculator. Formulas: Probability of event A occurring P (A) = n(A) / n(S). Probability of event A not occurring P(A') = 1 - P(A). Probability of event B occurring P(B) = n(B) / n(S). Probability of event B not occurring P(B') = 1 - P(B). Probability of both events occurring P(A ∩ B) = P(A) x P(B). Probability ...


Area (probability) = Area Under the Normal Distribution. Instructions. Specify the mean and standard deviation. Indicate whether you want to find the area above a certain value, below a certain value, between two values, or outside two values. Indicate the value(s). Hit tab, return, or the "recalculate button." The area will be ...
