Here's a simpler example. I randomly give you one card out of a full deck. The probability that that card is the A [img]/images/graemlins/spade.gif[/img] is 1/52 right?

Now what if I deal myself five cards, then deal you a card. The probability that the card I give you will be the A [img]/images/graemlins/spade.gif[/img] is still 1/52 because you don't know what my cards are, so you're still randomly getting one card out of 52. Get it?
