In a recent semester at a local university, 490 students enrolled in both General Chemistry and Calculus I. Of these students, 66 received an A in general chemistry, 58 received an A in calculus, and 30 received an A in both general chemistry and calculus. Find the probability that a randomly chosen student received an A in general chemistry or calculus or both.

Answer:

Probability chosen student received A in one or both = 0.191 (Approx.)

Step-by-step explanation:

Given:

Total number of student = 490

66 = received A in general chemistry

58 = received A in calculus

30 = received A in both general chemistry and calculus

Find:

Probability chosen student received A in one or both.

Computation:

Probability chosen student received A in one or both = 66/490 + 58/490 - 30/490

Probability chosen student received A in one or both = 94/490

Probability chosen student received A in one or both = 0.191 (Approx.)
