Equation to find probability

WebThe probability calculator multiple events uses the following formula for calculating probability: \text {Probability} = \dfrac {\text {Event}} {\text {Outcomes}} Probability = OutcomesEvent. The calculation of probability is initiated with the determination of an event. Every event has two possible outcomes. WebThe PROB function syntax has the following arguments: X_range Required. The range of numeric values of x with which there are associated probabilities. Prob_range Required. A set of probabilities associated with values in x_range. Lower_limit Optional. The lower bound on the value for which you want a probability. Upper_limit Optional.
