Step-by-step explanation:
Number of action movies = 7
Number of comedies = 12
Number of dramas = 2
Total movies = 7 + 12 + 2 = 21
Probability of selecting a movie that is not an action movie = movies that are not action movie/total movies
movies that are not action movie = total - action movies = 21 - 7 = 14
Probability of selectione a movie that is not an action movie = 14/21
In the lowest term:
Probability of selecting a movie that is not an action movie = 2/3
