 Probability of an Event
notes
Probability:

Probability is the extent to which an event is likely to occur.

Probability is the branch of mathematics that measures the uncertainty of the occurrence of an event using numbers.

It is expressed as a fraction or percentage using the following formula.

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event, and 1 indicates certainty.

The higher the probability of an event, the more likely it is that the event will occur.

For a random experiment, if sample space is ‘S’and ‘A’ is an expected event then the probability of ‘A’ is P(A). It is given by the following formula.
P(A) = `"Number of sample points in event A"/"Number of sample points in sample spaces" = "n(A)"/"n(S)"`.
