Question

Question 5: 11 ptsBruce took a survey of high school students to see how many had part-time jobs last summer. The results of thesurvey are shown in the table. Compare the probability that a student in the freshman class had a part-time jobto the probability that a student in the senior class had a part-time job.

Answer 1

By observing the given table, we get 19 freshers had job out of 60 students.

The probability of fresher had a summer job is

`F=(19)/(60)=0.317`

24 Senior had a job out of 69 students

The probability of senior having a summer job is

`S=(24)/(69)=0.348`

Comparing the probability values as follows.

`0.317<0.348`

A freshman is less likely than a senior to have a job.

Option first is correct.
