Exhaustive Events or Cases
The total number of possible outcomes of a random experiment is known as the exhaustive events or cases. For example,
(i) In tossing a coin, there are two exhaustive cases, viz., head and tail (the possibility of a coin standing on an edge being ignored).
(ii) In throwing a die, there are 6 exhaustive cases since any one of the 6 faces 1,2,…,6 may come uppermost.
(iii) In drawing two cards from a pack of cards, the exhaustive number of cases is 52C2, since 2 cards can be drawn out of 52 cards in 52C2 ways
