Now, obviously we’re going to have a tough time doing this at
the table. So, here are a few quicker methods to do this at the
table. We can look at the makeup of his range. About 25% of
the time he has a set.
6 / 22 = 0.27
So, the other 75% of the time he has the OESD. About 75% of
the time we have 66% equity, and 25% of the time we have 9%
equity. Here are four different methods to figure out our average
equity.
1. Find out what 3/4 of 66 is and what 1/4 of 9 is. Then
sum the results.
3/4 of 66 + 1/4 of 9 = Average Equity
49.5 + 2.25 = 51.75
2. You have 66% equity 3 times and 9% equity 1 time.
You can add those together and divide the sum by four.
((66 * 3) + (9 * 1)) / 4 = Average Equity
207 / 4 = 51.75
3. Find 3/4 of the way from 9 to 66. You can do this by
subtracting 9 from 66, and then dividing that result by 4.
Finally subtract that results from 66.
66 - 9 = 57
57 / 4 = 14
66 - 14 = 52
