Definition: 
A basic concept which may be taken either as indefinable, expressing in some way a “degree of belief”, or as the limiting frequency in an infinite random series. Both approaches have their difficulties and the most convenient axiomatisation of probability theory is a matter of personal taste. Fortunately, both lead to much the same calculus of probabilities.

Context: 
A probability is similar to a rate, the difference being that the denominator comprises all those objects in a given population at the beginning of the period of observation.
For example: If 10 people die in one year out of a population of 1 000 at the start of a year, the probability of dying during that year was 10/1 000, or 0.01000.
