Here is the definition of mathematical expectation which is also called as frequency or average number of times of occurrence of an event.
Suppose a random experiment is conducted independently 'n' times.
E is an event with probability P,
then out of n times approximate number of times of occurrence of event E is called mathematical expectation or frequency of E.
If the probability of any event E is P, then the frequency of E = n.P
Odds in favor of a event E are defined as P(E) to P(E)
Odds against E are defined as P(E) to P(E)
