  " Mathematics is a easy subject but maximum find them so hard to learn and remember Mathematics functions and rules. That all because we not give time to understand basics of Mathematics rule. So learn here the basic rules step by step." PROBABILITY "Probability is a numerical description of possibilities that an event can be occur." The probability of an event is a number between 0 and 1. '0' indicates impossibility of the event and '1' indicates certainty to find the probability of a single event to occur we need to know the total number of possible outcomes.  Probability can be written as decimal value or in percentage. The possibility of an event will be written as P ( E ) . 1. If P ( A )  › P (B) ; then event A has higher chance of occurring then event B.     If P ( A ) =  P (B) ; then event A and B are equally likely to occur. 2. If an event may happen 'X' ways and fails to happen in 'Y' ways in a trial ,      Then...

          Mathematics is a easy subject but maximum find them so hard to learn and remember Mathematics functions and rules. That all because we not give time to understand basics of Mathematics rule. So learn here the basic rules step by step. The first step to find understanding is learn about number and number system. Also divisibility rules so useful in solve questions. We find us uncomfortable if we not know as which number original number can be divide , that can be make easy if we know divisibility rules. Here all will describe in short notes so you can understand soon. 1. Types of Numbers : Following are the basic types of numbers :- 1. Natural Numbers  (N) = (1,2,3,4,...) 2. Whole Numbers  (W) = (0,1,2,3,4,...) 3. Integers  (Z) = ( … , -3,-2,-1,0,1,2,3 , … ) 4. Real Numbers  (R) = (23.057 , 0.057 , 0.5555 , 5/7 ,   √3 , -15 , 20 etc. ) 5. Rational Numbers  (Q) = ( 1/2 , -3/5 , 2/9 , 0/2 , 99/1...
