1. The problem statement, all variables and given/known data Given a unit square and a 'target' square of size LXL = p^2 < 1 in the unit square. The center of target square in equally likely to be anywhere in the unit square. What is the average size of the target square as a function of p^2. This is the problem and I have included a jpeg illustration of the problem. Any help would be greatly appreciated. My attempt at the problem : I divided the problem into three cases : one where the target square is completely in the unit square : one where half the target square is in the unit square and one where quarter of the target square is in the unit square. I then calculated the expectation integral of p^2 but I am confused as to what the probability density function is and what the limits of integral are for each of the cases.
