Find the probabilities
We can make a easy comparison by finding the percentage of the two
The percentage that a freshman has a summer job will be 64%
Now the seniors
26.2% of the seniors have a summer job.
So, the obvious comparison is that "a senior is less likely to have a job then a freshman" or the second option. Since the percentage that a freshman will have a job is much higher then the percentage a senior will have a job.
