Given a piecewise CDF FX(b) which is discontinuous at several points, find the probabilities at those points and also find the value of FX(b) at a continuous point and the expectation.
This cdf is a step function and is therefore the cdf of a discrete random variable. This should be stated somewhere in the statement or the solution. Apart from this the question is correct.
