At a certain university, 60% of the students enrolled in a math course, 50% are enrolled in an English course, and 40% are enrolled in both. What percentage of the students are enrolled in an English course and/or a math course?
Let M be a math course, E be an english course, We are given:
Using two event probability, we get P(E U M) = 0.7
Let M be a math course, E be an english course, We are given:
- P(M) = 0.6
- P(E) = 0.5
- P(E AND M) = 0.4
- We want P(E U M)
Using two event probability, we get P(E U M) = 0.7
