At Lewisville University, they are looking into how often students
attend football games. Here are the results:
● 45% of students regularly attend football games
● Of those that attend football games regularly, 35% are first-year
students and 64% are upper-class students.
● Of those that do not attend football games, 25% are first-year
students and 34% are upper-class students
What is the approximate probability that a randomly selected person
will be attending the football game given they are an upper-class
student?
