The experiment consists of tossing coins, each with probability of heads p, until either n heads occur or m tails occur. The event that n heads occur before m tails is indicated by the random variable I. On each update, the results of the coin tosses are shown in the first graph. On each update, the number of heads, the number of tails, and the value of I are recorded in the first table. The density of I is shown in blue in the second graph and is recorded in the second table. On each update, the empirical density of I is shown in red in the second graph and is recorded in the second table. The parameters n, m, and p can be varied with scroll bars. You may have to undock the toolbar to make all of the controls visible.

To add the applet to your web page, insert the following in the html file, at the point where you want the applet to appear:
<applet code="edu.uah.math.experiments.PointExperiment.class" archive="PointExperiment.jar"
width="600" height="400"></applet>
The jar file and the html file must be in the same folder.
This width and height dimensions are simply suggestions and can be varied. Generally, components such as graphs and tables expand and contract proportionally, while components such as buttons, scrollbars, dice, and coins are fixed in size.
