seven movies (A, B, C, D, E, F, and G) are being scheduled for showing. The order of the showing is determined by random selecton. find the probability that film C will be shown first, film A next-to-last, and film E last.
--------------------
# of ways to select 1st film: 1
# of ways to select 6th film: 1
# of ways to select 2,3,4,5, and 7th film: 5! = 120
--------------------------
# of ways to get the pattern you want: 1*1*120 = 120 ways
--------------
# of ways to make the selections without restriction: 7! = 5040
-----------------------------------------------
Probability = 5!/7! = 1/(6*7) = 1/42
