How often do suited cards flop a flush draw?
Suited hole cards flop a flush draw (exactly two more of the suit) 10.94% of the time, and a made flush 0.84% — about 1 in 8.5 flops for a draw or better.
You hold two of the thirteen cards in a suit; eleven remain. A flush draw needs exactly two of them among the three flop cards and one card of another suit: C(11, 2) × 39 = 2,145 of the 19,600 flops, just under 11%. A flopped flush needs all three: C(11, 3) = 165 flops, 0.84%.
Being suited adds a little under 3 percentage points of equity to a hand preflop. Most of that comes from these 11% of flops, where the draw then completes about 35% of the time by the river.
