Since the weight of bricks is uniformly distributed between 1 and 1.5 pounds, the range of possible weights is 0.5 pounds. The probability that one brick weighs more than 1.3 pounds is the length of the interval from 1.3 to 1.5 pounds divided by the total interval length (1.5 - 1 = 0.5), which is (1.5 - 1.3) / 0.5 = 0.4. The probability that two bricks independently each weigh more than 1.3 pounds is 0.4 * 0.4 = 0.16.
