Your answer is partially correct. Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 137 disks are summarized as follows: Shock Resistance High Low Scratch High 64 15 Resistance Low 12 46 Let A denote the event that a disk has high shock resistance, and let 8 denote the event that a disk has high scratch resistance. If a disk is selected at random, determine the following probabilities. Round your answers to two decimal places (e.g. 98.76). (a] P(A) = 0.55 (b) P(B) = 0.58 (c) P(A] - 0.45 (d) P(AnB) - 0.47 (e] P(A U B) - 0.66 () PA'UB) - 42
