Re: probability of coin toss

I am having a difficult time trying to figure what is
the best method to
calculate the probability of a number of unbiased
coin tosses.

Example: What is the probability of tossing 90 heads
out of 100 coin tosses?

Any insight would be greatly appreciated!
Nick



It6'sd the binomial probability of 90 out of 100 when p = 1/2.

[100!/(90!*10!)]/(2^100)
