poor bastard, we are confusing the **** out of him.
and by the way using the method i use its 4 times number of outs and subtract the number of outs in excess of 8. so
15*4-(15-8)=53%.
OR if you want something even better, which compensates for the error in estimates then use the above posters method:
this excerpt from wikipedia explains further:
[edit] Approximating odds after the flop
With two cards to come, the percent chance of hitting one of x outs is about 4x. This approximation gives roughly accurate probabilities for up to about 12 outs, with an absolute average error of 0.9, a maximum absolute error of 3, a relative average error of 3.5, and a maximum relative error of 6.8.
A slightly more complicated, but significantly more accurate approximation of drawing outs after the flop is to use 4x only for 1 to 9 outs, and (3x+9) for 10 or more outs. This approximation has a maximum absolute error of less than 1 for 1 to 19 outs and maximum relative error of less than 5 for 2 to 23 outs.
[edit] Approximating odds after the turn
With one card to come, the percent chance of hitting one of x cards is about 2x. This approximation has a constant relative error of an 8 underestimation, which produces a linearly increasing absolute error of about 1 for each 6 outs.
A more accurate approximation is (2x+(2x÷10). This is easily done by first multiplying x by 2, then rounding the result to the nearest multiple of ten, and adding the 10's digit to the first result. For example, to calculate the odds of hitting one of 12 outs on the river: 12 × 2 = 24, 24 rounds to 20, so the approximation is 24 + 2 = 26. This approximation has a maximum absolute error of less than 0.9 for 1 to 19 outs and a maximum relative error of 3.5 for more than 3 outs.
