Assume that for a particular tire, the probability of lasting 30,000 miles (or more) is 0.75. For someone who buys a set of four of these tires, what is the probability that she will have to replace at least two of them before reaching 30,000 miles? You may use the binomial distribution, but comment on why it might not be a suitable model in this case.
