Each rear tire on an experimental airplane issupposed to be filled with a pressure of 40 pound per squareinch (psi). Let X denote the actual air pressure for the right tireand Y denote the actual air pressure for the left tire. Suppose that Xand Y are random varibles with the jointdensity
f (x, y) = k (x^2+y^2, 30<-x<50;
30<-y<50
0, elsewhere
a.) find k
b.) find P (30<-x<-40 and 40<-Y<50)
c.) Find the probability that both tires areunderfilled.
