A classical point particle moves back and forth with constant speed between two walls at x = 0 and x = 10 cm. What is the probability of finding the particle between
X = 4.0 cm and x = 5 cm?
A) 0.01
B) 0.04
C) 0.07
D) 0.10
E) 0.14

The particle moves with constant speed, so it spends equal time in equal intervals. The interval from 4.0 cm to 5.0 cm is 1 cm long, and the total distance between the walls is 10 cm. Thus, the probability is 1 cm / 10 cm = 0.10.
