The corporation is sure that it will take no more than 7 days for this installation and check to take place. Let A be the event "it will be more than 4 days before the machinery becomes available" and B be the event "it will be less than 6 days before the machinery becomes available." a. Describe the event that is the complement of follows: S = [E, E2, E3, E4, Es, Eg, E7, Eg, Eg, E10] Given A = [E, E3, E, Eg], define A. Given A = [E, E3, E7, Eg] and B = [E, E, Eg, E,]. 3.1 3.2 a.
