On Friday I posted this puzzle…..
Imagine that 4 cards have been removed from a pack of 52 cards and placed face down in front of you. If you were to choose any two of the four, the chances of getting two red cards is 50%. What are the chances of picking a black pair?
If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
The chances are…… zero. In order to have a 50:50 chance of getting a pair of red cards, three of the four have to be red!
Did you solve it? How?
