Answer:
The ratio of the number of bulbs tested to defective bulbs is always 14 to 1.
<u><em>What is the unitary method?</em></u>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We generally expect industrial processes to produce defects at about the same rate, the proportion of the defective product is generally considered to be a remain constant.
Here, the proportion of defective bulbs is:
1/14 = 2/28 = 6/84
So, it will be 24/336.
The ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.

Answer:
The probability that exactly one switch is good is
Step-by-step explanation:
The probability that a switch is defective is:
The probability that a switch is not defective is
Therefore, if two switches are selected, the probability that exactly 1 is good is:
