1.13. Problem. (Section 3.4) Three black boxes are labeled with Roman numerals I, II and III. • Box I contains four red chips and three blue chips. • Box II contains two red chips and five blue chips. • Box III contains seven red chips and no blue chips. Solve each of the following problems.

(a) Suppose a box is selected at random and three chips are drawn at random from the box. If all three chips are red, what is the probability they were drawn from Box I?

(b) Suppose one chip is selected at random from each box. If two of the three chips drawn are red chips, what is the probability that the chip drawn from Box II was red?

(c) Suppose three chips are randomly selected from Box I and placed in Box III. If a chip subsequently drawn randomly from Box III is blue, what is the probability that all three chips moved from Box I to Box III were blue.

Lightbulbs are manufactured by three factories, I, II, and III. 10% of the lightbulbs were made in factory I. 40% of the lightbulbs were made in factory II. 50% of the lightbulbs were made in factory III. Suppose that 3% of the lightbulbs produced by factory I are defective. 1% of the lightbulbs produced by factory II are defective. 2% of the lightbulbs produced by factory III are defective. If a randomly selected lightbulb is defective, what is the probability...
