#11During the spring semester, \"many\" years ago, 300 SUNY engineering students enrolled in both Calculus II and Physics I. Of these students, 90 earned an A in calculus, 66 earned an A in physics, and 45

Solution

the probability that a randomly chosen student earned an A in at least one of the two courses

= P(CalculusUPhysics)

= 90/300+66/300-45/300

= 111/300

= 0.37
