WebThe binomial probability calculator will calculate a probability based on the binomial probability formula. You will also get a step by step solution to follow. Enter the trials, probability, successes, and probability type. Trials, n, must be a whole number greater than 0. This is the number of times the event will occur. WebTo find the standard deviation, use the formula σ = √n ⋅ p ⋅ (1 − p) where n is the umber of trials and p is the probability of success on a single trial. Substituting values fo this problem, we have σ = √5 ⋅ 0.65 ⋅ (1 − 0.65) Evaluating the expression on the right, we have σ = √1.1375) σ = 1.0665364503851. To complete a ...
