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.)
