Answer
A
W X Y Z 0.10 0.20 0.30 0.40
B
W X Y Z 0.40 0.40 0.40 0.40
C
W X Y Z 0.25 0.25 0.25 0.25
D
W X Y Z 0.50 0.50 0.50 –0.50

Explanation

There are 4 movies, and the random method makes each one equally likely. Each movie therefore has probability 1 ÷ 4 = 0.25. Choice C gives W, X, Y, and Z a probability of 0.25 each.
