Question
Transcribed Image Text:3.44 Each rear tire on an experimental airplane is
supposed to be filled to a pressure of 40 pounds per
square inch (psi). Let X denote the actual air pressure
for the right tire and Y denote the actual air pressure
for the left tire. Suppose that X and Y are random
variables with the joint density function
f(2, 4) = {0
Sk(a? + y?), 30 < # < 50, 30 <y < 50,

elsewhere.
(a) Find k.
(b) Find P(30 <X < 40 and 40 <Y < 50).
