This problem is a review of your knowledge of expressing fractions. Let's say we have 40 students enrolled in a Stat 200 class: 1/5 live outside the U.S., 25% have a slow internet connection, and 12 are under age 30. Write all the ages on separate pieces of paper, put them in a hat and blindly draw one out, what are the chances (probability) that age would be under 30 years?
