2. A survey conducted at a local high school indicated that 30% of students have a job during the school year.
If having a job and being in the eleventh grade are not independent, what do you know about the probability that a
randomly selected student who is in the eleventh grade would have a job? Justify your answe.

The two events mentioned here are "having job" and "studying in eleventh grade". It is mentioned in the statement that having a job and studying in eleventh grade are not independent .

The criteria of independence using conditional probability is P(A/B)=P(A).

According to given situation, it means that P(having job/studying in eleventh grade) is not equal to the P(having job). Hence the if the selected student is studying in the eleventh grade changes the probability of having job. So the probability that the student studying in the eleventh grade would have job will be not equal to 0.30.
