The problem of points experiment is a random experiment that consists of tossing coins, each with probability of heads , until either heads occur or tails occur. The event that heads occur before tails is indicated by the random variable . On each update, the results of the coin tosses are shown in the coin box. On each update, the number of heads, the number of tails, and the value of are displayed in the record table. The probability density function of is shown in blue in the distribution graph and is recorded in the distribution table. On each update, the empirical probability density function of is shown in red in the distribution graph and is recorded in the distribution table. The parameters , , and can be varied with scroll bars.
