For two values c and d, where a ≤ c ≤ d, the area of the red region equals the probability that x lies between c and d. For a uniform distribution from a = 1 to b = 25, find the probability that
(a) x lies between 2 and 8.
(b) x lies between 4 and 12.
(c) x lies between 5 and 17.
(d) x lies between 8 and 14.
