Binomial Distribution

number of tosses n

10

probability p of head on each toss

0.5

If a coin that comes up heads with probability

p

is tossed

n

times, the number of heads observed follows a binomial probability distribution. Move the sliders and watch how the distribution changes. The mean of the distribution—the number of heads one "expects" to observe—is marked with an orange circle on the horizontal axis.
