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

useful-resources-probability-cbse-class-10-2

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.

CBSE Class 10 Probability Important Formulas and concepts for exams

Equally likely events : Two or more events are said to be equally likely if each one of them has an equal chance of occurrence.
 
Mutually Exclusive events : Two or more events are mutually exclusive if the occurrence of each event prevents the every other event.
 
Complementary events : Consider an event has few outcomes. Event of all other outcomes in the sample survey which are not in the favourable event is called Complementary event.
 
Exhaustive events : All the events are exhaustive events if their union is the sample space. 
 
Sure events : The sample space of a random experiment is called sure or certain event as any one of its elements will surely occur in any trail of the experiment.
 
Impossible event : An event which will occur on any account is called an impossible event.
