Ans: We can use Angle sum property:
A + B + C + D = 360
A + 3x + 2x + 5x = 360
A + 10x = 360
A = 360/10x= 36x
A = 36x
6 and 12 are two common factors
Answer:
Last option is the correct answer.
Step-by-step explanation:
Total number of movies = 9+7+4=20
The total number of combinations of choosing 3 movies from total 20 is represented by 20C3. Then there are 9 action movies and we're choosing 3, the number of combinations will be 9C3,
Now, the probability of choosing all action movies will be:

As we know that probability of something which is not happening is given as : 1 - probability of something happening, so the probability of not choosing all action movies is given by: 
Hence, option D or last option is the right one.
9:20 + 3:00= 12:00
12:00 + 0:50= 12:50 A.M. Tom's afternoon shift begins
