Our proof of Theorem \(1.8 .1\) was for the discrete case. The proof for the continuous case requires some advanced results in in analysis. If in addition, though, the function \(g(x)\) is one-to-one, show that the result is true for the continuous case. Hint: First assume that \(y=g(x)\) is strictly increasing. Then use the change of variable technique with Jacobian \(d x / d y\) on the integral \(\int_{x \in \mathcal{S}_{x}} g(x) f_{X}(x) d x\)
Let \(X\) have the pdf \(f(x)=(x+2) / 18,-2
A bowl contains ten chips numbered \(1,2, \ldots, 10\), respectively. Five chips are drawn at random, one at a time, and without replacement. What is the probability that two even-numbered chips are drawn and they occur on even- numbered draws?
Find the cdf \(F(x)\) associated with each of the following probability density
functions. Sketch the graphs of \(f(x)\) and \(F(x)\).
