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 \(\rho .\)
Find \(P\left(0
A fair die is cast at random three independent times. Let the random variable \(X_{i}\) be equal to the number of spots that appear on the \(i\) th trial, \(i=1,2,3\). Let the random variable \(Y\) be equal to \(\max \left(X_{i}\right) .\) Find the cdf and the pmf of \(Y\). Hint: \(P(Y \leq y)=P\left(X_{i} \leq y, i=1,2,3\right)\).
Let \(X_{1}\) and \(X_{2}\) have the joint pdf \(h\left(x_{1}, x_{2}\right)=2
