you have an aversion to working with negative numbers,
we highly recommend that you customize the count.
Customizing means tailoring the IRC and key count
values, and it can be done so that you never have
to count with negative numbers. It's an easy process
that's explained in Appendix 8, along with a specific
example of a count customized for the K-O Rookie.
if the man were willing to pay us $6 if we rolled
a six, the bet would seem to be fair, and if the payout
were $7, the game would run in our favor. If you can
follow this reasoning, congratulations! You've just
performed an expectatiorl calculation.
Now let's write out that expectation calculation explicitly.
The amount of money that we will win or lose on average
from any bet is called expected value. It is a function
of three things: First, every time we play, we know
we will lose the $l that we pay. We will express this
loss, which happens 100 percent of the time, as a
negative number. Second and third are the two possible
outcomes of the die roll: if we roll a six, we win
$5, and if we roll a one, two, three, four, or five,
we win nothing.
