1070

Attended College Did not Attend Total
Satisfied with job 325 186 511
Not satisfied with job 190 369 559
Total 515 555 1070

If you were to randomly sample an individual from this population, find the probability of selecting an individual who is
a. satisfied with job
b. did not attend college given not satisfied with the job
c. not satisfied with job, and did not attend college
