# What kind of distribution shows percents of heads in a series of coin tosses?

If you plotted the percentage of heads after a series of coin tosses, and let the number of coin t ossesp er trial go to infinity, and the number o f trials go to infinity,y ou would get somethingl ike an ormal distribution, right? But it would be centered at 50% and have endpoints at 0% and 100% (i.e. not negative infinity and infinity) so it wouldn't really be a normal distribution, right? What would this be called?

Binomial distribution, which is a series of Bernoulli trials. This converges to normal dist as number trials approaches infinity.
