In a piston assembly, the specifications for the clearance between piston rings and the<br>cylinder wall are very tight. In a lot of assemblies, let X be the number with too little<br>clearance and let Y be the number with too much clearance. The joint probability mass<br>function of X and Y is given in the table below:<br>У<br>х<br>0.15<br>0.12<br>0.11<br>0.10<br>0.09<br>0.07<br>0.05<br>0.04<br>2<br>0.06<br>0.05<br>0.04<br>0.02<br>0.02<br>3<br>0.04<br>0.03<br>0.01<br>
