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.
