A study on class demographics found that 60% of the students are engineering majors, 20% are mathematics majors, and 5% are studying both engineering and math. Suppose a random student from class is chosen. Let E stand for the event that an engineering student is selected and let M stand for the event that a mathematics major is selected. Suppose a random student is selected. Calculate the following. (a) P(MC) = 0.8 (b) P(E or M) = 0.75 (c) P(E...
