The following table shows the number of students in three different degree programs and whether they are graduate or undergraduate students:
Degree Program | Undergraduate | Graduate | Total |
Business | 150 | 50 | 200 |
Engineering | 150 | 25 | 175 |
Arts & Sciences | 100 | 25 | 125 |
Total | 400 | 100 | 500 |
What is the probability that a randomly selected student is an undergraduate?
Solution:
Given that
The following table shows the number of students in three different degree programs and whether they are graduate or undergraduate students:
Degree Program | Undergraduate | Graduate | Total |
Business | 150 | 50 | 200 |
Engineering | 150 | 25 | 175 |
Arts & Sciences | 100 | 25 | 125 |
Total | 400 | 100 | 500 |
We have to find the probability that a randomly selected student is an undergraduate:
Probability that student selected is a undergraduate = total no of undergraduate students / total no' of students
Probability that student selected is a undergraduate = 400 / 500
Probability that student selected is a undergraduate = 0.8
Therefore the probability that a randomly selected student is an undergraduate is 0.8
