There are 15,750 visitors at the football stadium. One of them is to be selected at random to win a prize. If the probability that a woman will be selected is 2/63, what is the number of women at the stadium?
  1. 400
  2. 450
  3. 500
  4. 550
  5. 600
Explanation
Answer: C - The number of women at the football stadium is 500. A probability of 2/63 means that of every 63 visitors 2 are women. Use a proportion to find the number of women among 15,750 visitors.
2:63=x:15,750
63x=15,750×2
x =(15,750×2)/63=250×2=500
