Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! A basket contains cards with the numbers 1 through 10. There are two cards for each number.
If 2 cards are randomly chosen from the basket without replacement, what is the probability that the first card will be a 7 and the second card a 2?
Ans: (2/20)(2/19) = (1/10)(2/19) = 2/190 = 1/95
