Measurements are made of the length L and width W of a rectangular part. Assume that L ∼ U(9.95, 10.05) and W ∼ U(4.9, 5.1), and that they are independent random variables. For each of the following events: a) express them using set notation, b) draw them in the joint sample space of (L, W) and c) calculate their probability. (a) The length is less than 9.98. (b) The length is between 9.96 and 9.98 and the width is between 5.0 and 5.05. (c) Either the length is between 9.96 and 9.98, or the width is between 5.0 and 5.05.
