As an incoming freshman, Marcus believes that he has a 25% chance of earning a GPA in the 3.5 to 4.0 range, a 35% chance of graduating with a 3.0 to 3.5 GPA, and a 40% chance of finishing with a GPA less than 3.0. From what the pre-med advisor has told him, Marcus has an eight in ten chance of getting into medical school if his GPA is above 3.5, a five in ten chance if his GPA is in the 3.0 to 3.5 range, and only a one in ten chance if his GPA falls below 3.0. Based on those estimates, what is the probability that Marcus gets into medical school?
