PROBABILITY

Experimental or empirical probability P(E) of an event E is

The theoretical probability (also called classical probability) of an event A, written as P(A), is defined as

Two or more events of an experiment, where occurrence of an event prevents occurrences of all other events, are called Mutually Exclusive Events.

COMPLIMENTARY EVENTS AND PROBABILITY

We denote the event 'not E' by E . This is called the complement event of event E.

So, P(E) + P(not E) = 1

 ♦ The probability of an event which is impossible to occur is 0. Such an event is called an impossible event.

 ♦ The probability of an event which is sure (or certain) to occur is 1. Such an event is called a sure event or a certain event.

 ♦ The probability of an event E is a number P(E) such that 0 ≤ P (E) ≤ 1

 ♦ An event having only one outcome is called an elementary event. The sum of the probabilities of all the elementary events of an periment is 1.

DECK OF CARDS AND PROBABILITY

A deck of playing cards consists of 52 cards which are divided into 4 suits of 13 cards each.They are black spades (♠) red hearts (♥), red diamonds (♦) and black clubs (♣).

The cards in each suit are Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3 and 2. Kings, Queens and Jacks are called face cards.
