RE: Daily Brain Games (Mar 15) - how witty are you?

in #contest7 years ago

The possibility is pretty high that at least one that is flipped will be a king, but a slightly better chance there won’t be.
Here’s why:
The first card you flip you have a 1/3 (33.33%) chance of a king and 2/3 chance of not flipping it.
The second card you flip, the chances increase if the first one was not a king to 2/5 (40%) and 3/5 (60%) chance of not getting a king.
The probability of not getting a king is higher.

Sort:  

Well, your arguments look good, but there is a slight misunderstanding. It says above that

"you pick two cards randomly"

which means, that you pick two cards and not one plus one.

So @cryptobserver is the winner today.
Thanks for participating anyway!

Ah. Ok. I’ll try again tomorrow.
Good puzzle today. Thanks.

Thank you! Seeya!
