3.44 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.
