Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are summarized as follows: shock resistance scratch resistance high high low 70 low 16 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. Input your answers in the fractional form (do not simplify). Input your answer up to 2 decimal places. eg. 0.52 or 0.40 P(A) = Blank 1 %3D P(B) = Blank 2 P(A ') = Blank 3 P(An B) = Blank 4
