Math Probab.
posted by Jane .
In a standard deck of 52 playing cards there are 13 hearts. If 3 cards are drawn from the deck ( WITHOUT REPLACEMENT, what is the probab. that all 3 cards will be hearts? which below and why?
A (13/52)cubed
B (13/52)(12/51)(11/50)
C (13/52)(13/51)(13/50)
D (13/52)(12/52)(11/52)

We all know that before we draw the first heart, there are 13 hearts out of 52 cards.
Think of how many hearts are left after the first (successful) draw, and how many cards are left in the deck for the second draw.
If you're not sure, post your answer for a check.
