In our case, n is the number of tosses in each trial, and p=0.5 is the chance of a coin landing heads up. So the mean of 1000 tosses is 500, as expected. The variance of a binomial distribution is n p (1 - p). So the standard deviation (in our case) is the square root of n, divided by 2. iron rod through skull
