Answer:
10.5%
Step-by-step explanation:
The probability that a student took an accounting course, P(A)= 28.3%
The probability that a student took a statistics course P(A)= 31.3%
The probability that a student took accounting and statistics course,
![P(A \cap S)=49.1\%](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20S%29%3D49.1%5C%25)
We want to determine the probability that a randomly selected student took an accounting or statistics course, ![P(A \cup S)](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20S%29)
In probability theory,
![P(A \cup S)=P(A)+P(S)-P(A \cap S)\\P(A \cup S)=28.3\%+31.3\%-49.1\%\\P(A \cup S)=0.283+0.313-0.491\\P(A \cup S)=0.105](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20S%29%3DP%28A%29%2BP%28S%29-P%28A%20%5Ccap%20S%29%5C%5CP%28A%20%5Ccup%20S%29%3D28.3%5C%25%2B31.3%5C%25-49.1%5C%25%5C%5CP%28A%20%5Ccup%20S%29%3D0.283%2B0.313-0.491%5C%5CP%28A%20%5Ccup%20S%29%3D0.105)
The probability that a randomly selected student took an accounting or statistics course is 0.105 or 10.5%.
85.5 as a fraction is 85 2/10 which is simplified to 85 1/5
