Question

Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 129 disks are summarized as follows: Shock Resistance High Low Scratch High 66 14 Resistance Low 1435 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) (b) P(B) = (d) P(An B) (e) P(A U B) = (f) PIA U B)- 0.88
