Homework Statement
Probability a student gets an A on the midterm is 13.96%
Probability a student gets an A on the final is 13.12%
Probability a student gets an A on both the final and the midterm is 5.7%
What is the probability that a student doesn't get an A on the final or the midterm?
Homework Equations
3. The Attempt at a Solution [/B]
I would think that the probability of not getting an A on the final or the midterm would be $$P(a_{M}^c)+P(a_{F}^c)-P(a_{F}^c \space \space \mbox{&}\space \space a_{M}^c)$$ Unfortunately I'm not sure what the probability of not getting an A on both the midterm and the final is. Also I'm confused as to why the probability that a student gets an A on the final and the midterm is 5.7%, shouldn't that be equal to Probability of an A on the midterm*probability of an A on the final?
