Find angle between plane Π1, given by three points, and the plane Π2 given in Cartesian form.
The calculation of cos(α) at the end of Advice has fractionNumbers switched on and so the result is presented as a fraction, which can be misleading. Best if calculation is followed through without using fractionNumbers.

Question in Content created by Newcastle University
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.
