4 Flush after flop. What are the odds of getting the flush?

[Toddy]

Does anyone know what the odds of hitting the flush if you have 4 after the flop?

35%

Odds of hitting flush on turn with 4 on flop = 9/47 (19.1%)
Odds of hitting flush on river after not hitting it on flop = 38/47 x 9/46 (15.8%)

Total odds = 35%

or.......................

percent chance of hitting flush with 2 cards to come = 1 - (percent chance of NOT hitting flush)

1 - (38/47 X 37/46) ~= .35
