Two methods of measuring surface smoothness are used to evaluate a paper product. The measurements are recorded

Question:

Two methods of measuring surface smoothness are used to evaluate a paper product. The measurements are recorded as deviations from the nominal surface smoothness in coded units. The joint probability of the two measurements is a uniform over the region 0 < x < 4, 0 < y, and x – 1 < y < x + 1. That is, fXY (x, y) = c for x and y in the region. Determine the value for c such that fXY (x, y) is a joint probability density function.
