3.44 Each rear tire on an experimental airplane issupposed to be filled to a pressure of 40 pounds persquare inch (psi). Let X denote the actual air pressurefor the right tire and Y denote the actual air pressurefor the left tire. Suppose that X and Y are randomvariables with the joint density functionf(2, 4) = {0Sk(a? + y?), 30 < # < 50, 30

Given,f(x,y)=k(x2+y2) ; 30≤x≤50 , 30≤y≤500 elsewhere
