A probability question.?

Question

A particle (in the classical sense) with constant energy, restricted to one dimension, bounces back and forth between barriers at x=0 to x=L.

Without observing the path of the particle's movement. What is the probability of finding the particle at an arbitrary point in the region 0 <= X <= L?

Answer 1

1/L

Answer 2

Since the location of the particle is continuous on the range of 0 to L, then P(X=x) = 0 for any value x between 0 and L. That means that the probability that you find the particle at arbitrary point is 0.

Answer 3

At an arbitrary point I would say zero.
