Probability question: N times in M trials
Playing at a table where Blackjacks didn't seem to be coming up as often as they "should" got me wondering how to solve this probability question:
If the probability of a certain outcome is P in a single trial, what is the probability of that outcome at least N times M trials?
(Also, is it correct that the probability of it not happening at least N times is 1 minus that number?)
