Probability and Statistical Inference 9
(Michigan Mathematics Prize Competition, 1992, Part II) From the set \(\{1,2,3, \ldots, n\}\), \(k\) distinct integers are selected at random and arranged in numerical order (from lowest to highest). Let \(P(i, r, k, n)\) denote the probability that integer \(i\) is in position \(r\). For example, ob

In Metro, there are three types of houses: E (expensive), M (medium), and C (cheap). Each household prefers the same spending on public education. Schools are initially financed with the property tax based on market value, and initially there are three school districts. Suppose the property tax is re
