(C) The total number of cards is $100$. Thus,the total number of possible outcomes is $100$.$A$ number is a perfect square if it is of the form $n^2$. The perfect squares between $1$ and $100$ are: $1^2=1, 2^2=4, 3^2=9, 4^2=16, 5^2=25, 6^2=36, 7^2=49, 8^2=64, 9^2=81, 10^2=100$.There are $10$ such numbers.Therefore,the number of favourable outcomes is $10$.The probability of drawing a perfect square is $\frac{	ext{Favourable outcomes}}{	ext{Total outcomes}} = \frac{10}{100} = \frac{1}{10}$.

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