  1. In suffling a pack of card 3 are accidentally dropped then the chance that missing card should be of different suit is ?
    1. 169/425
    2. 261/425
    3. 104/425
    4. None of these
Correct Option: A

Total ways 52C3 = 22100
There are 4 suit in a pack of cards so three suit can be selected in 4C3 ways.
One card each from different unit can selected as = 13C1 X 13C1 X 13C1 ways
So, favourable ways = 4C3 X 13C1 X 13C1 X 13C1 = 8788
∴ Required probability = 8788/22100 = 169/425
