## Probability of an Event – Formula and Examples

Here you will learn what is the probability of an event formula with examples. Let’s begin – Probability of an Event Definition : If there are n elementary events associated with a random experiment and m of them are favourable to an event A, then the probability of happening or occurrence of A is denoted …

## Total Probability Theorem – Definition and Examples

Here you will learn law of total probability theorem with examples. Let’s begin – Total Probability Theorem (Law of Total Probability) Let an event A of an experiment occurs with its n mutually exclusive and exhaustive events $$B_1,B_2,B_3….B_n$$ then total probability of occurrence of event A is P(A) = $$P(AB_1)$$ + $$P(AB_2)$$ +……..+ $$P(AB_n)$$ P(A) …

## Multiplication Theorem Probability

Here you will learn formula for multiplication theorem probability with examples. Let’s begin – Multiplication Theorem Probability It is called compound probability or multiplication theorem. It says the probability that both A and B occur is equal to the probability that A occur times the probability that B occurs given that A has occurred. If …

## Probability Basic Concepts

Here, you will learn probability basic concepts and definitions of probability. Let’s begin – Probability gives us a measure of likelihood that something will happen. However probability can never predict the number of times that an occurrence actually happens. Probability Basic Concepts and Definitions (a) Experiment : An action or operation resulting in two or …
