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 (that is, each pair of motors has the same chance of being selected). find the probability that: a. both motors will operate satisfactorily in the capsule. b. one motor will operate satisfactorily and the other will not.

A.

B.

Step-by-step explanation:

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. Then

To fabricate a new capsule, 2 motors will be randomly selected (that is, each pair of motors has the same chance of being selected).

A. The probability that both motors will operate satisfactorily in the capsule is

B. The probability that one motor will operate satisfactorily and the other will not is

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
