Which of the following events are independent, which are disjoint, and which are neither independent nor disjoint?
a) A = Your telephone number is randomly selected. B = You're not at home at dinnertime when they call.
b) A = As a selected subject, you complete the interview. B = As a selected subject, you refuse to cooperate.
c) A = You are not at home when they call at 11 a.m. B = You are employed full-time.
