If A and B are events associated with a random experiment having sample space S and if , then
If A and B are mutually exclusive events associated with a random experiment having sample space S, then If are mutually exclusive events associated with a random experiment, thenIf A and B are mutually exclusive and exhausive events associated with a random experiment having sample space S, then
If are mutually exclusive and exhaustive events associated with random experiment having sample space S, thenIf A and B are any two events associated with a random experiment having sample space S, then
If A and B are any two events associated with a random experiment, then
Probability of occurence of A only
Probability of occurence of B only
is the probability of occurence of only (or exactly) one of the two events A and B.
If A, B and C are any three events associated with a random experiment, then
If odds in favour of an event A are a:b then If odds against an event A are a:b then If probability of an event is p then odds in favour are
