A factory has two assembly lines, each of which is shut down (S), at partial capacity (P), or M full capacity (F). The sample space is given in Figure 1.25, where, for example. (S, P) denotes that the lust assembly line is shut down and the second one is operating at partial capacity. What is the probability that
(a) Both assembly lines are shut down?
(b) Neither assembly line is shut down?
(c) At least one assembly line is at full capacity?
(d) Exactly one assembly line is at full capacity? What is the complement of the event in part (b)? What is the complement of the event in part (c)?
