Probability

The answer is 1 in 72193.

This calculation is actually much simpler than the odds of a triple, and it's actually simple enough to easily do without a calculator. A straight flush can begin at 1 (ace) up to 9 (since we don't want to include the royal flush which starts at 10), therefore there are 9 possible straight flushes for each suit, and there are 4 suits. Therefore, the total number of straight flushes is 9*4=36. Therefore, we can divide the total number of combinations (2598960) by 36 to get the odds of a straight flush: 1 in 72193.
