I haven't figured out these numbers before, but I'll assume yours are correct. With a one gap, lets say 79, you will hit an open-ender with 68x, 8Tx, you will hit a gut shot with 8Jx, 85x, 56x, or TJx, so twice the odds of an open-ender(10.58%), you will hit a belly buster with 58J, 356, or TJK(if you count all belly-busters), so about (4/48) *(3/2) *(5.29) = 0.78% or so.

Use the same process for two gaps.
