This calculator helps you find the probability of at least one success in a given number of trials n and probability p using the formula:
Probability of one success = 1 - (1-p)ⁿ
You need to provide the n and p values, then click the ‘Calculate’ button below:
P(at least one success): 0.91765
Steps:
P(at least one success) = 1 – (1-0.3)7
P(at least one success) = 1 – (0.7)7
P(at least one success) = 0.91765
