ABSTRACT
In games of chance, probability has a very intuitive definition. For instance, the people know what it means that the chance of a pair of dice coming up seven is 1 in 6. Probability theory is useful in many other contexts and, in particular, in areas that depend on data affected by chance in some way. The word probability is used in everyday language. A more tangible way to think about the probability of an event is as the proportion of times the event occurs when the people repeat the experiment an infinite number of times, independently, and under the same conditions. Computers provide a way to actually perform the simple random experiment described above: pick a bead at random from a bag that contains three blue beads and two red ones. In the 1970s, there was game show called “Let’s Make a Deal” and Monty Hall was the host. The theory described requires repeating experiments over and over forever.
