What are the types of business statistics?

Basic Probability Rules

Probability Rule One (For any event A, 0 ≤ P(A) ≤ 1)
Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
Probability Rule Three (The Complement Rule)
Probabilities Involving Multiple Events.
Probability Rule Four (Addition Rule for Disjoint Events)
