What type of events are always dependent?

• A. Independent events
• B. Complementary events
• C. Mutually exclusive events
• D. Random events

Answer: (C)

Dependent events are events where the outcome of one event affects the outcome of another event. In this context, mutually exclusive events are always dependent because if one event occurs, it completely rules out the possibility of the other event occurring at the same time. For example, when flipping a coin, if it lands on heads, it cannot simultaneously land on tails. The occurrence of heads directly impacts the situation, confirming that tails cannot occur in that instance. Therefore, mutually exclusive events inherently exhibit dependency because the occurrence of one event dictates the non-occurrence of the other. In contrast, independent events would not affect each other's outcomes. Complementary events encompass the scenario where one event occurs while the other does not, but they depend on the total outcome set rather than on each other directly. Random events simply pertain to events characterized by unpredictability, not necessarily implying dependency or independence.
