3. At Fred Scruntley's Automotive Works the arrivals of customers at the Complaints Desk are recorded.
Let X be the number of disgruntled customers arriving on a typical day. It is found that the cumulative
distribution function of X is:
. if x < 1
0.1 if 1<x < 2
0.4 if 2< x < 4
0.6 if 4 < x < 7
0.9 if 7< x < 10
1 if 10 <x.
F(x) =
(a) Calculate the probability mass function of X and draw its plot.
(b) Using just the cumulative distribution function of X, compute P(2 < X < 7), P(X < 10) and
P(X > 5).
