Answer:
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
