Quick probability question

[KingOHearts]

How far off center of the bell curve is it to see 121 hands without seeing a PP once?

And I quit too, so who knows how long it would have continued.

[jbark]

the probability of no PPs in 121 consecutive hands is .0006 or .06%

Why do I come up with something totally different?

Chance of not getting a pocket pair = 48/51
So it's just (48/51) to the 121st power? Or am I losing my mojo?

[Dave B]

Hey Adam, you get the same thing.



48/51=.94118

.94118^121=.0006522

[Adamm]

Whoops. You're right.
