Question 1123868: An engineering school reports that 50% of its students were male (M), 36% of its students were between the ages of 18 and 20 (A), and that 30% were both male and between the ages of 18 and 20.
What is the probability of choosing a random student who is a female or between the ages of 18 and 20? Assume P(F) = P(not M).

50% are male, so 50% are female.

The answer is 80%.
