Probability
Calculates the probability of exceeding a given number of hits for a collection of Bernoulli trials, which is a test with a binary result (e.g. yes/no, 1/0, heads/tails). User inputs a vector of probabilities of success for each trial, p, and a number of successes, h, and this function outputs...
