Suppose the following is known about students in their first year of a Mathematics program at university, regarding the introductory Calculus (C), Linear Algebra (L), and Statistics (S) courses:



80% of students take Calculus

77% of students take Linear Algebra

20% of students take Statistics

65% of students take Calculus and Linear Algebra

5% of students take Linear Algebra and Statistics

16% of students take Calculus and Statistics

4% of students take Linear Algebra, Calculus, and Statistics.

Suppose we randomly select a citizen in this city. Answer the following questions:



What is the probability that this student is studying Calculus or Linear Algebra?

What is the probability that, out of these three courses, this student is only studying Statistics?
