Chances of holding an Ace?

[J.A.K.]

With 2 callers preflop, what are the chances one of them holds an Ace? (I do not hold one)


Is 36% in the ball park?

[Copernicus]

a priori they collectively have 16 "outs" in 50 cards or roughly 32%. (the precise number is (1 - combin(46,4)/combin(50,4)) = 29%.

However the fact that they called narrows their range of hands significantly if they are good players, and Aces may actually compose a much larger percentage of their range of calling hands.
