Q. 4

Students who live in the dorms at a college get free T.V. service in their rooms, but only receive 6 stations. On a certain evening, a student wants to watch T.V. and the six stations are broadcasting separate shows on baseball, football, basketball, local news, national news, and international news. The student is too tired to check which channels the shows are playing on, so the student picks a channel at random. On a different night, two students who don't know each other each choose a channel this way. The two events, N = the first student watches a news broadcast  and F = the second student watches football are
 a. independent events.
  b. disjoint (mutually exclusive) events.
  c. each simple events.
  d. None of the above.
