" kelly has twelve cards numbered 1 to 12. what is the probability of picking three evennumbered cards consecutively, if the first two cards are not replaced?

6/12 * 5/11 * 4/10

I DID 7*7*6=294. 294/1728=49/288.
IM PROBABLY WRONG, THOUGH
SO LISTEN TO STEVE. 
Doesn't it have to be 7/12*6/11*5/10??

no, it's 1,3,5,7,9,11
and
2,4,6,8,10,12 
SORRY!

But how about the replaced portion?
I don't get this 
YA I DON'T GET IT EITHER. SO IT IS 6/12*5/11* NOT BY 4/10 BECAUSE IT IS BEING REPLACED, RIGHT???
SO CONFUSED AUSSI...
