Let \(X_{1}, X_{2}, X_{3}\), and \(X_{4}\) be four independent random variables,
each with pdf \(f(x)=3(1-x)^{2}, 0
Let \(X\) and \(Y\) have the joint \(\mathrm{pmf} p(x, y)=\frac{1}{7},(0,0),(1,0),(0,1),(1,1),(2,1)\), \((1,2),(2,2)\), zero elsewhere. Find the correlation coefficient \(\rho .\)

Suppose that a man leaves for work between 8:00 A.M.and 8:30 A.M. and takes between 40 and 50 minutes to get to the office. Let \(X\) denote the time of departure and let \(Y\) denote the time of travel. If we assume that these random variables are independent and uniformly distributed, find the probability that he arrives at the office before \(9: 00\) A.M..
