Properties of probability i) 0 ≤ P(A) ≤ 1. ii) P(ɸ) = 0, P(S) = 1. iii) For any two events A and B, P(AUB) = P(A) + P(B) – P(A∩B), where AUB is read as ‘A

## What is the difference between conditional probability and probability?

In short, “Each conditional probability is a probability and the converse is also true.” The 1st part of the above statement is obvious but how is the converse true? To understand things better, let us first revisit
