Question

Victor took a survey of high school students to see how many had part-time jobs last summer. The results of the survey are shown in the table. Compare theprobability that a student in the sophomore class had a part-time job to the probability that a student in the junior class had a part-time job.

Answer 1

A sophomore is less likely than a Junior to have a job.

Step-by-step explanation:

Given the table in the attached image.

The total number of sophomores is

`35`

The number of sophomores with a job is;

`12`

The probability that a sophomore had a job is;

`P_S=(12)/(35)`

The total number of Juniors is

`37`

The number of Juniors with a job is;

`27`

The probability that a Junior had a job is;

`P_J=(27)/(37)`

From the derived Probability, we can observe that the probability that a Junior had a job is greater than the probability that a Sophomore had a job.

`P_J>P_S`

Therefore, A sophomore is less likely than a Junior to have a job.
