A refreshment stand sells popcorn and soft drinks. Of the 100 students who came to the movie, 62 bought popcorn and 47 bought a drink. 38 students bought both popcorn and a drink.
What is the probability that a student buys a drink?
To find the probability that a student buys a drink, we need to divide the number of students who bought a drink by the total number of students.
There were 47 students who bought a drink.
Therefore, the probability that a student buys a drink is 47/100 = 0.47 or 47%.
