Advanced Options - Texas Instruments Probability Simulation User Manual

Advanced Options

The advanced options section allows you to change the probabilities for each
outcome. This could be used to simulate unfair dice and weighted coins, for
example. The advanced options section can be reached by pressing the ' ADV'
key in the options screen for the coin, dice, marbles, and spinner sections.
8.1 Weights
The left column in the advanced options screen represents the relative
weight of each outcome. The weight for an outcome can be from 0 to 999.
The probabilities on the right column of the screen will automatically be
recalculated whenever the weight values are changed.
8.2 Probability
The right column contains the probability for each outcome, and is
automatically updated when the weights are edited. Alternatively, the
probabilities may be edited and the weights will be automatically
calculated. Please note that the resulting probabilities may be slightly
different in the forth decimal place as it may not be possible to represent
the probabilities exactly with only 3 digit weight values. To edit
probabilities, press the right arrow key until the cursor is positioned in the
right column. As you enter the probabilities from top to bottom, the
bottom rows will be adjusted so that the sum of the probabilities for all
outcomes is exactly one. Therefore, the last row will be automatically
calculated, so it is not necessary to enter the value.
