if you toss a coin 36 times what would the standard deviation for the number of heads that will be tossed
The coin toss experiment is a binomial distribution,
with p=1%2F2, q=1%2F2, n+=+number+_of+_tosses+=36.
The standard deviation SD for the binomial distribution is:
SD+=sqrt%28npq%29
SD+=+sqrt%2836+%2A+%281%2F2%29+%2A+%281%2F2%29%29
SD+=+sqrt%289%29
SD+=+3
