Answer by greenestamps(13200) (Show Source): You can put this solution on YOUR website!

The range of values on which the function is defined is from 0 to 2, a length of 2.

The prescribed range of values is from 1 to 1.5, a length of 0.5.

Since the probability density is constant on the whole range, the probability that x is between 1 and 1.5 is

ANSWER: 0.25,or 1/4, or 25%
