11-2 Applications
The RANDINT( (random integer) function can be used for probability
experiments. RANDINT( takes two arguments that define a set of integers from
which to draw for the probability experiments below.
Using RANDINT( from the MATH PRB menu, devise
probability experiments that employ the toss of a coin, the roll
of two dice, and the spin of a wheel.
For the coin tossing experiment, enter RANDINT(0,1) from the
Home screen. 0 = tails and 1 = heads. Press ¸ repeatedly
to generate the coin tosses.
You can also write a simple program to display “heads” or
“tails” for each coin toss.
You can simulate the rolling of two dice by adding together
the result from each die after a roll. On the Home screen,
enter RANDINT(1,6)+RANDINT(1,6) and press ¸
repeatedly.
You can simulate spinning a wheel with the numbers 1 to 100
using the RANDINT( function. Enter RANDINT(1,100) on the
Home screen and press ¸ repeatedly.
