In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from to , and one SuperBall is drawn (at random) from ten red balls numbered from to . When you buy a ticket, you choose three numbers from to and one number from to .
If the numbers on your ticket match at least two of the white balls or match the red SuperBall, then you win a super prize. What is the probability that you win a super prize?
(So far I tried the answers 1/3,1/7200, 317/2500, 1/567, 229/400,1/92, but none of them are correct.)
