What are the odds of flopping a flush?

The odds of being dealt a straight flsuh are 1 in 64,974 as for being dealt one on the flop.. Not sure..

It depends on your hole cards. The best odds are with mid range suited connectors, specifically 45s to JTs. For example, with 45s, you have 4 possible ways of flopping a straight flush (A23s, 236s, 367s, and 678s). Since you are holding 2 cards, there are 50 possible cards that can fall on the flop, creating 19,600 flops. (calculated as 50!/{[50-3]!*[3!]} ) That being given: 19,600/4 = 4900, or a '1 in 4900' chance.

So the odds of flopping a straight flush while holding a mid range suited connecter are 1 in 4900.
