TABLE 6-1
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 Table 6-1, 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) A randomly selected computer on a given day will either require a repair or will not.
C) 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.
D) The probability that two or more computers that will require repair in a given day approaches zero.

The property required for using the binomial distribution is that there are only two possible outcomes for each trial (in this case, a computer either requires repair or does not require repair) and the trials are independent. Choice B satisfies this requirement by stating that a randomly selected computer on a given day will either require repair or will not. The other choices are not relevant to this requirement.
