Worksheet #21 - Probability Game
Spring 2007
Objectives
•Learn how your calculator can simulate the rolling of a pair of dice.
•Learn how histograms and probability density functions are related.
•Learn how to measure the fairness of a game.
Problem #1 - For two dice, you will need two random numbers (between 1 and
6) to be generated. The RAND (generates uniformily distributed real numbers
between 0 and 1) and iPart (extracts the integer part of a number) will assist in
creating dice simulator.
•RAND can be found on your calculator under MATH, then PRB, then
Option 1. iPart can be found on your calculator under MATH, then NUM,
then Option 3.
•Use these functions to create a function that produces random integers be-
tween 1 and 6. This simulates one die. Write this function:
iPart( 6*RAND +1)
•You can use the 2nd-Entry to repeat previous calculator entries. So, instead
of typing in the function again and again, you can recall it with only a few
keystrokes.
•Roll two dice. Fill in the chart below with 60 random numbers that simulate
two dice rolling. How did you simulate two dice?
•Come back after completing the two-dice experiment. Roll three dice. Fill in
the chart below with 100 random numbers that simulate three dice rolling.
How did you simulate three dice?
