when sum of probabilities of two events are equal to 1, then the events are called

Dear student, 
Mutually exclusive events will have a probability of zero. All inclusive events will have a zero opposite the intersection. All inclusive means that there is nothing outside of those two events: P(A or B) = 1. Therefore when sum of probabilities of events is equal to 1, the events are all inclusive. 

Regards,
