A random variable X has cumulative distribution function
FX(t) ={0                                          t < 1
           1/2t − 1/2                             1 ≤ t < 2
           1/2                                       2 ≤ t < 3
           1/2t − 1                                3 ≤ t < 4
           1                                          4 ≤ t

What is the range of X?

Compute the probability that |X − 2.5| ≤ 1.

Compute the PDF of X.
