Assume that you have the following probabilities for your final grade in your econometrics course, with the standard GPA scale of A=4, B=3, C=2, D=1, F=0 applies (ignoring +/- for simplicity). Letting Y be your grade, P(Y=4)=0.2, P(Y=3)=0.5, and P(Y<3)=1-0.2-0.5=0.3. The expected value E(Y)=
Homework Answers
We know,
Corresponding to probability P(Y<3) we need Y value in
calculation of expected value. In this range of Y i.e. for
representative value of Y is (0+1+2)/3 = 1
