but, I guess I want to make sure I am on the right math track.

Let' say we have 39 marbles in a jar, 12 each red, yellow, and blue. 3 black. Is the proper formula for say, choosing and removing 3 yellows in a row, without returning removed marble to the jar, be:

(12/39)*(11/38)*(10/37)

or .02407

Thanks, and sorry for being a moron

Yes, (12/39)*(11/38)*(10/37) is the probability of choosing 3 yellows in a row from that jar without replacement.

Well, we all know that, since you can't even spell "Idiot" !










For the record, I realize that it was a typo, and you can't edit the thread title, but I got a good laugh out of it!

Maybe the spelling error was made on purpose for comedic purpose.
