Dealing with normal (Gaussian) distribution

I basically stucked on rather simple problem: Toss N coins and discover, how many of them land heads Solution performance must not depend on N, so we can't just call Math.random() < 0.5 N times. Obviously, there is Gaussian distribution to the…

Do you have a better idea to simulate coin flip?

Right now i have return 'Heads' if Math.random() < 0.5 Is there a better way to do this? Thanks edit: please ignore the return value and "better" means exact 50-50 probability.

Code to count times to get all heads or all tails is returning only times to get heads

I am pretty happy to say I think I have my first coin flip problem running. I am counting how many times it takes to get all heads or all tails in a trial of 7 flips. In theory it should take around 64 times to get either all heads or all…
