According to Table 12-2, the average proportion of time all servers are busy is 0.833. Therefore, the proportion of time at least one server is busy is 1 – 0.833 = 0.167. However, it is important to note that the question asks for the proportion of time at least one server is busy, not the proportion of time all servers are busy, which may be a common mistake. Therefore, the best choice is D: 0.909.
