Hi!
When you break the rule for the first time, de probability distribution of X is constant in [0, 2], and is zero outside. If the the value obtained is X = a, then the probability distribution of Y (conditioned on X = a) is constaint in interval [0, a], and zero outside. Then the region in the X-Y plane where the joint density is non-zero is the filled triangle in the figure.
Answer:
300 in2
Step-by-step explanation:
area of 2 identical triangle + area of 3 rectangle = surface area
(5*12/2)*2 + 8*12 + 5*8 + 8*13 = 300 in2
