Two events are mutually exclusive if they cannot occur simultaneously, meaning if one event occurs, then the other cannot occur. This is also known as the "either/or" scenario. Option A refers to events that overlap on a Venn diagram, which indicates that they are not mutually exclusive. Option C describes events that are not necessarily mutually exclusive, but rather dependent events, where the probability of one event affects the probability of the other. Option D combines both incorrect options, so B is the correct choice.
