Hi Shailaja
In order to solve probability questions , you need to clear your basics of Permutations and Combinations.
Probability is nothing but calculating favourable cases and total possible cases. All this involves the application of PnC. So if yu want to be good at probability, firstly you need to be good at permutations and combinations. So first work on that.
