In a recent semester at a local university, 500 students enrolled in both general chemistry and calculus i. of these students, 66 received an a in general chemistry, 73 received an a in calculus, and 33 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.

Step-by-step explanation:

Given: In a recent semester at a local university, students enrolled in both General Chemistry and Calculus. Of these students, received an A in general chemistry, received an A in calculus, and received an A in both general chemistry and calculus.

To Find: Find the probability that a randomly chosen student received an A in general chemistry or calculus or both.

Solution:

Total number of students in university

Total number of students received A in General Chemistry

Total number of students received A in calculus

Total number of students received A in General chemistry and calculus both

Probability that a randomly selected student got A in General Chemistry

Probability that a randomly selected student got A in Calculus

Probability that a randomly selected student got A in General Chemistry and calculus

Probability that a randomly chosen student received A in general chemistry or calculus or both

Hence the probability that a randomly chosen student received an A in general chemistry or calculus or both is
