Simulating Die Throws
=
The faces of a cubical die are numbered from one to six. The probability of getting any one of
these numbers is
6
1
. Here we would like to suggest a way of simulating series of throws,
using the Ran# function of
fx-350MS, without using the actual die.
Procedure
1. Set your calculator to COMP mode.
2. Key in 16Ran#+ , that is: followed by
You will probably see something similar to the screen on
the right. (
Your displayed result may be different.)
3. Continue pressing . Notice that for each press of , the displayed output
will change.
4. To simulate 5 throws (five times), first key in the formula 16Ran#
+
and press .
Suppose you get the display on the right. By taking the
unit digit, i.e. 5, the first throw is 5.
Next, we press

Hence, our simulation generates the throws of 5, 3, 6, 2, 6. Your simulation may generate
different outputs.
