Web26 okt. 2014 · Fundamental laws of probability The probability of an event A is a number P (A) which satisfies the following three conditions: • 0≤P (A)≤1, i.e. probability is a measure that is restricted between 0 and 1. • P (S) = 1, where S is the sample space. That is, the universal set is the sure event. 3.
