Probability of “At Least One” Calculator

by Tutor Aspire
The formula to find the probability of “at least one” success in a series of n trials is calculated as:
P(at least one success) = P(failure in a given trial)n
This calculator finds the probability of at least one success, given the probability of success in a single trial and the total number of trials.


P(at least one success) = 1 – P(failure in a given trial)n

P(at least one success) = 1 – (0.96)3

P(at least one success): 0.11526
