In a drawing for a dvd player, there are 100 tickets in a box.Five of the cards are marked with a star and the rest are marked with an X. To win, Carmen must draw two cards, without replacement, both of which are marked with a star. What is the probability that Carmen will win the dvd player?

(5/100)*(5/100)=25/10000=0.0025 or .25%
