The door prize at a dance includes 4 - $10 gift certs, 5 $20 certs and 3 $50 certs. 5 prizes are drawn at random, what is the prob. that none of the prizes is a $10 gift cert ?
I dont remember a thing about this type of questions.
I am trying my best and will edit the post with whatever i got =)
Oh yes..>I see it now !!!
Thanks alot for the jump start....
Its the formula to find the prob. in a hyper geometric distribution.
I couldnt figure out a way to use that formula with that question..
Guess i am approaching questions the wrong way...
Thanks alot again sir.
