Flush probability

[deepsquat]

When u hit a 4 flush on the flop, the odds of making that flush by the river are 35% correct? If the turn card misses, what odds are you to get the flush card on the river? 17.5%?

thanks

Yes.

(make it on the turn) + (make it on the river) =
(9/47) + (38/47)*(9/46) =
19.15% + 15.82% = 34.97%

So, more 4-flushes are made on the turn than on the river.

As you can see, it's not half of 35%. Off the top of my head, I can't think of a meaningful question related to this situation where the river and turn probabilities are equal.
