" kelly has twelve cards numbered 1 to 12. what is the probability of picking three even-numbered 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
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...
