Greg saved $8,000 prior to starting college. Each semester he must pay $2,5000 in tuition and fees. He knows he will eventually be in debt. What is the equation and how much debt Greg will be in if he graduates in 4 years (8 semesters) ?

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
