Instruction 6.8
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 Instruction 6.8,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 two computers will require repair on a given day?
A) 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.
B) A randomly selected computer on a given day will either require a repair or will not.
C) The probability that a computer that will require repair in the morning is the same as that in the afternoon.
D) The probability that two or more computers that will require repair in a given day approaches zero.

The binomial distribution can be used only when there are a fixed number of independent trials, each with two possible outcomes (success or failure), and the probability of success remains constant across all trials. In this case, the fixed number of trials is the number of computers (125), and the two possible outcomes are either a computer requiring repair or not requiring repair. The probability of a computer requiring repair is constant across all computers and is given as 0.15. Therefore, option B is the correct choice as it states one of the necessary conditions for the binomial distribution to be applicable.
