Binomial
Experiment Lab

Choose the number of trials n and the probability of success p, then run the experiment repeatedly. The observed relative frequencies build up as solid bars over the theoretical Binomial distribution, extending the idea of the die-roll convergence tool from a single probability to the shape of a whole distribution.
