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 low
high 70 9
low 16 5

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.

a. P(A)=86/100
b. P(B)=79/100
c. P(A')=7/50
d. P(A U B)=95/100
e. P(A' U B)= ???
