DISJOINT OR MUTUALLY EXCLUSIVE EVENTS:- Two events, A and B, are disjointed or mutually exclusive when they don’t have an element in common. If outcome A is to obtain an even number from a die and B is to obtain a multiple of 5, A and B are mutually exclusive events.

INDEPENDENT EVENTS:- Two events, A and B are independent if the probability of the succeeding event is not affected by the outcome of the preceding event. By rolling a die twice, the results are independent.
DEPENDENT EVENTS : – Two events, A and B are dependent if the probability of the succeeding event is affected by the outcome of the preceding event. For example, two dependent events would be drawing two cards (one at a time) without returning them to the deck.

COMPLEMENTARY EVENT : –
The complementary event of A is another event that is realized when A is not realized. It is denoted by Ā or A. for example, the complementary event of obtaining an even number when rolling a die is obtaining an odd number.
