Okay the game is texas holdem, you have 1 card to come. The math below allows us to calculate the percentage of your card turning pretty accurately, max varince of 1.5%.

Very little brain usage required, essential in my case!

12+ Outs: (Outs X 2) + 2 = % of hitting

3-11 Outs: (Outs x 2) + 1 = % of hitting

1-3 Outs: Outs x 2 = % of hitting

Outs / Actual Percentage / Our easy to calculate %

20 43.50% 42%

19 41.30% 40%

18 39.10% 38%

17 37.00% 36%

16 34.80% 34%

15 32.60% 32%

14 30.40% 30%

13 28.30% 28%

12 26.10% 26%

11 23.90% 23%

10 21.70% 21%

9 19.60% 19%

8 17.40% 17%

7 15.20% 15%

6 13.00% 13%

5 10.90% 11%

4 8.70% 9%

3 6.50% 6%

2 4.30% 4%

1 2.20% 2%

Example we have 5 outs, so we times 5 by 2 to get 10 and +1 for an 11% chance of hitting 1 of our cards. actual 10.90%.

Alot of poker players will just work to a rule of x2 but doing it like this gives us a little edge and edges are good in poker! The problem I am having is finding a similar soultion for the following percentages (2 cards to come)..... So just wondering if any great math brains can help me find something similar to the above but practical to use.

20 67.5%

19 65.0%

18 62.4%

17 59.8%

16 57.0%

15 54.1%

14 51.2%

13 48.1%

12 45.0%

11 41.7%

10 38.4%

9 35.0%

8 31.5%

7 27.8%

6 24.1%

5 20.3%

4 16.5%

3 12.5%

2 8.4%

1 4.3%

again x4 seems to be the best for outs 1 - 8, 36% is acceptable for 9 outs but its from 10 onwards that i cant find any "simple" consistency that i could use in a simlar manner.

Thanks
