guessing cards

[qpw]

Assuming you didn't do anything so baroque as guessing either of his cards were the same as the ones you held:

There are 50 unknown cards after yours are dealt so each guess would have a (4/50*4/49) chance of success = 0.6531%

Doing it twice would have a 0.004264% chance of success.

It should thus happen around 1 time in 23,500 attempts.

So if every poker player in the world tried it every day, you would expect the feat to be reproduced many times a day.

Order doesn't matter here, so multiply your value by 2.

Quite correct.

You do in fact have <u>8</u> chances in 50 of getting one of the two cards for the first selection then 4/49 of getting whichever you did not get the first time in the second.
