On a large construction site the lengths of pieces of lumber are rounded off to the nearest centimeter. Let X be the rounding error random variable (the actual length of a piece of lumber minus the rounded-off value). Suppose that X is uniformly distributed over [-0.5,0.5]. Find (a) P(-.10X.20); and (b) V(X).
