Among 500 freshmen pursuing a business degree at a university, 315 are enrolled in an economics course, 213 are enrolled in a mathematics course, and 123 are enrolled in both an economics and a mathematics course. what is the probability that a freshman selected at random from this group is enrolled in each of the following? (enter your answers to three decimal places.) (a) an economics and/or a mathematics course(b) exactly one of these two courses(c) neither an economics course nor a mathematics course

Step-by-step explanation:

Given that among 500 freshmen pursuing a business degree at a university, 315 are enrolled in an economics course, 213 are enrolled in a mathematics course, and 123 are enrolled in both an economics and a mathematics course.

From the above we find that

a) either economics of Math course is

Out of 500 students 405 have taken either Math or Economics

Hence

c) student who have taken neither =

Exactly one course is either math or economics - both

=

1 + (6 / x - 1)
