SCENARIO 6-7
A company has 125 personal computers.The probability that any one of them will require repair on a given day is 0.15.
-Referring to Scenario 6-7,which of the following is one of the properties required so that the binomial distribution can be used to compute the probability that no more than 2 computers will require repair on a given day?
A)The probability that a computer that will require repair in the morning is the same as that in the afternoon.
B)The number of computers that will require repair in the morning is independent of the number of computers that will require repair in the afternoon.
C)The probability that any one of the computers that will require repair on a given day will not affect or change the probability that any other computers that will require repair on the same day.
D)The probability that two or more computers that will require repair in a given day approaches zero.

For the binomial distribution to be applicable, each trial (in this case, the functioning of each computer on a given day) must be independent of the others. Choice C correctly states that the probability of one computer requiring repair does not affect the probability of another computer requiring repair, which is a requirement for the independence of trials in a binomial distribution.
