CRITBINOMCalculates the smallest value for which the cumulative binomial distribution is greater than or equal to a specified criteria.
CRITBINOM(num_trials, prob_success, target_prob)
num_trials – The number of independent trials.
prob_success – The probability of success in any given trial.
target_prob – The desired threshold probability.
PROB: Given a set of values and corresponding probabilities, calculates the probability that a value chosen at random falls between two limits.
BINOMDIST: Calculates the probability of drawing a certain number of successes (or a maximum number of successes) in a certain number of tries given a population of a certain size containing a certain number of successes, with replacement of draws.
