In a lottery there are 10 prizes and 25 blanks. A ticket is drawn at random. What is the probability of winning a prize?

Explanation:
Probability is the ratio of favorable outcomes to total outcomes. Here there are 10 winning tickets and 25 blanks, for a total of 35 tickets. Since each ticket is equally likely to be drawn, the chance of getting a prize is 10 out of 35, which simplifies to 2/7. So the probability is two-sevenths.
