Linda and Billy need to schedule appointments with the same doctor. Linda calls in the morning and picks one of the open appointment times. In the afternoon, Billy calls to schedule one of the remaining appointment times.

Question

are these two events independent and dependent

Answer 1

These two events are dependent because the availability of appointment times for Billy is affected by the choice Linda made earlier in the day. If Linda had chosen a different appointment time, that appointment time would no longer be available for Billy to schedule.
