"If it's so easy then YOU write up the solutions." I'm keeping an update on the right column of my blog on which problem he's got up to. <BR/><BR/>The answer to your particular problem, I believe, is that you have five different possibilities for the first choice. Five cards = five possibilities. Once you choose the first card you'll be left with four possible cards to choose from (5 X 4) then three cards will be left..( 5 X 4 X 3) and then down to one. This is where the "factorial" comes in handy. 5! <BR/><BR/>And you read that very loudly, like this <B>FIVE !</B>Anonymousnoreply@blogger.com
