A card is drawn at random from a pack of 100 cards numbered 1 to 100. The probability of drawing a number which is a square is

As a card is to be drawn from 1 to 100.


n(S) = 100


As we know that largest no less that or equal to 100 which is a perfect square = 100


And, √100 = 10


there are total 10 numbers from 1 to 100 which are square.


n(E) = 10


Hence,


P(E) = 10/100 = 1/10


As our answer matches only with option (c)


Option (c) is the only correct choice.
