Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 118 disks are summarized as follows: Shock Resistance High Low Scratch High 54 13 Resistance Low 12 39 Let A denote the event that a disk has high shock resistance, and let B 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) = i (b) P(B) = 1 (c) P(A) = ₁ (d) P(ANB) = (e) P(AUB) = (f) P(A'U B) = i i
