Sir,

 

    Though i am able to follow P&C well, i am unable to understand PROBABILITY.. Someone plz help me..

If you are comfortable with P&C, you shouldn't be having problems with probability. Try sloving easier problems (firstly single coin, die n then cards). once you are you are confident solving these,  move on to difficult problems(pairs of coins, dice n cards).

 

just understand the basic concept of sample space(favourable events) n total outcomes..

 

believe me, its not as difficult as much it looks. n don't be afraid of the complicated problems. you'll master them once you get to know of the strategy... keep practicing... Good Luck!!!!
