Odds question

[BarryP]

I'd like to know what the odds are of 2 players having a flush by 5th st. I know it must be very low, but I'd like to be more precise.
Thanks in advance.

are these five cards each, like in stud or draw

or 2 cards each plus three community cards

or 2 cards each, with three monotone community cards


these are all different questions, so rephrase yours please.

it might help to know the game

Sorry guy's that was stupid of me. The game is NLHE, full table, 3-4 players in to 5th st. and we're using both our hole cards.

Thanks.
BTW, would the odds be any different if there were 2 callers or even 1 caller?

ugh i used to be able to do this but it seems ive forgot how

i'm tired and don't feel like reworking the calculation, BUT...

from what i just ran real quick, assuming 4 players and no four-card flushes, the probability that at least two players having a flush by the river is approximately .2%

if anyone wants to double-check that feel free...

18 to one against them having the same suited cards
37/45 / 5= 84/100
37/44 / 4= 79/100
37/43 / 3= 72/100
47792/18000000
.0024
or about 500to1 against
