Question

Q1. (a)The next generation
of miniaturized wireless capsules with active locomotion will require two miniature electric motors
to maneuver each capsule. Suppose 10 motors have been fabricated but that, in spite of tests
performed on the individual motors, 2 will not operate satisfactorily, when placed into a capsule.
To fabricate a new capsule, 2 motors will be randomly selected, find the probability that:
I
(i)
(ii)
Both motors will operate satisfactorily in the capsule.
One motor will operate satisfactorily and the other will not.​

Answer 1

Answer:

see this answer

Step-by-step explanation:

The next generation of miniaturized wireless capsules with active locomotion will require two miniature electric motors to maneuver each capsule. Suppose 10 motors have been fabricated but that, in spite of tests performed on the individual motors, 2 will not operate satisfactory when placed in a capsule. To fabricate a new capsule, 2 motors will be randomly selected(that is, each pair of motors has the same chance of being selected.) Find the probability that: A: Both motors will operate satisfactory in the capsule. B:One motor will operate satisfactory in the capsule and one will not.
