(a)   =  =  = 2002 possible combinations.    ANSWER




(b)   =  = 0.41958  (rounded).    ANSWER  




(c)  The complementary event is 5 judges with no actors (i.e. all judges are musicians)

     The probability for this complementary event is  P' =  =  = 0.002997  (rounded).   ANSWER

     Therefore, the probability of the event under the question is 

          1 - P' = 1 - 0.002997 = 0.997003  (rounded).

Solved.
