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
