Toss the set of n coins.

The measured probability P(r) is the number of occurrences of r heads divided by the number of tosses, N.

It gives the measured probability distribution.

If you tossed the set many times (® ¥)you would get the binomial distribution for p = ½ and the particular value of n.

Vary N to see how the measured distribution approaches the theoretical one as N gets larger.
