What's the probability that the first card is black?

$\displaystyle \frac{26}{52}$

And now that you have 1 of the black cards, there are only 25 left out of 51, so the product of these is our answer

$\displaystyle \frac{26}{52}\cdot\frac{25}{51}$

whatever that comes out to be - Oct 14th 2009, 02:04 PMCaptainBlack
