Edit Question
Title
Body
I have a probability problem, which I need to simulate in a reasonable amount of time. In simplified form, I have 30 unfair coins each with a different known probability. I then want to ask things like "what is the probability that exactly 12 will be heads?", or "what is the probability that AT LEAST 5 will be tails?". I know basic probability theory, so I know I can enumerate all (30 choose x) possibilities, but that's not particularly scalable. The worst case (30 choose 15) has over 150 million combinations. Is there a better way to approach this problem from a computational standpoint? Any help is greatly appreciated, thanks! :-)
