machine break- downs

6.89  A student has a box containing 25 computer  disks, of which 15 are blank and 10 are not. She randomly se- lects disks one by one and examines each one, terminating the process only when she finds a blank disk. What is the probability that she must examine at least two disks? (Hint: What must be true of the first disk?)

6.90 In a school machine shop, 60% of all machine break- downs occur on lathes and 15% occur on drill presses. Let E denote the event that the next machine breakdown is on a lathe, and let F denote the event that a drill press is the next machine to break down. With P(E) = .60 and P(F) = .15, calculate:

a.    P1EC 2

b.    P1E ´ F2

c.    P1EC  ¨ FC 2
