Rogelio is attending career day at a local college. There are 30 professionals speaking at the event; 5 are from the law enforcement profession, 4 are from the military, 3 are from the teaching profession, 8 are from the medical and dental professions, 6 are from the business and accounting professions, and 4 work in politics. If Rogelio chooses two seminars to attend (each given by a different professional), what is the probability that he will attend a seminar on the law enforcement profession followed by a seminar on politics?
