K There are five seats available in a sedan. In how many ways can five people be seated if only four can drive? Use the generalized multiplication principle to find the number of ways the passengers can be seated. Suppose that a task consists of t choices performed consecutively. Suppose that choice 1 can be performed m ways; for each of these, choice 2 in m2 ways; for each of these, choice 3 in m3 ways; and so forth. Then the task can be performed in m m M3 ...mt ways. The first choice is to select the person to drive the sedan. How many ways are there to select the driver?
