Chapter 2, Problem 4(choose chapter or problem)
In a piston assembly, the specifications for the clearance between piston rings and the cylinder wall are very tight. In a lot of assemblies, let X be the number with too little clearance and let Y be the number with too much clearance. The joint probability mass function of X and Y is given in the table below:
a. Find the marginal probability mass function of X.
b. Find the marginal probability mass function of Y .
c. Are \(X \text { and } Y\) independent? Explain.
d. Find \(\mu_{X} \text { and } \mu_{Y}\).
e. Find \(\sigma_{X} \text { and } \sigma_{Y}\).
f. Find \(\operatorname{Cov}(X, Y)\).
g. Find \(\rho(X, Y)\).
