This is the same program as this one: https://community.ca...lator-fx-5800p/

C is the count of experiments you did.

B is the probability of an experiment being successful.

A is the number of successes you had during those C experiments.

Given these three it will tell you what is the probability that you'd get at least the same number of successes by pure chance. For example if you get a result of 0.994 that means that there's a 6/1000 chance that your successes were the result of pure luck.

Additionally if you give 0 for A, it will instead tell you how many successes you'd need to have in order for the result to by less than 1% probable to be pure luck.
