Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 139 disks are summarized as follows: 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. 0.98). P F f P(AB)= P(AB)= P(AB)=
