Point me to ...

the direction that talks about Choose function. I really do not understand it.

Thanks.

denoted "x Choose y" or C(x,y)=x!/(y! (x-y)!)
if i remember it right
hope it helps

in case you didnt know ! stands for factorial.

ie 6!=6*5*4*3*2*1
and 0!=1 by definition as does 1!=1

Oh no, i know all about factorials and such. But i just do not see how c(50,3) can tell you how many flops 52 cards can have. I dont' understand how you derive x and y numbers

C(50,3) is how many flops 50 cards can have. 50 ways to pick the first card, times 49 ways to pick the second card, times 48 ways to pick the third card. Then divide by 3! different ways each 3 card combination can be ordered so that we count each combination only once. So C(50,3) = 50*49*48/3!, and this is the same as 50!/(50-3)!/3!.

OOOOOOOOOOOOOOOOOOOOOOOOOOoooooooooooooo... i feel as though a light JUST went off in my head. It all makes sense now.

Thanks SO much [img]/images/graemlins/smile.gif[/img]
