In a recent semester at a local university, 540 students enrolled in both General Chemistry and Calculus I. Of these students, 51 received an A in general chemistry, 59 received an A in calculus, and 30 received an A in both general chemistry and calculus. Find the probability that a randomly chosen student did not receive an A in general chemistry.

    Step-by-step explanation:

    We are given;

    Number of students enrolled in both General Chemistry and Calculus I = 540 students

    Number of students who received an A in general chemistry = 51 students

    Number of students who received an A in calculus = 59 students

    Number of students who received an A in both general chemistry and calculus = 30 students

    Now, we want to find the probability that a randomly chosen student did not receive an A in general chemistry.

    So, first of all let's calculate number of students who didn't receive an A in chemistry.

    So,

    No without A in chemistry = 540 - 51 = 489 students

    So, probability that a randomly chosen student did not receive an A in general chemistry = 489/540 = 0.9056
