A company has 125 personal computers. The probability that any one of them will require repair on a given day is 0.025. To find the probability that exactly 20 of the computers will require repair on a given day, one will use what type of probability distribution?
A) Binomial distribution
B) Poisson distribution
C) Hypergeometric distribution
D) None of the above.

The scenario fits the criteria for a binomial distribution, which involves a fixed number of trials (125 computers), each with only two possible outcomes (require repair or not), and a constant probability of success (0.025). Therefore, the probability of exactly 20 computers requiring repair can be calculated using the binomial probability formula.
