(A) Let $S$ be the sample space of drawing a card from $100$ cards. Thus,$n(S) = 100$.Let $A$ be the event of drawing a number which is a perfect square.The perfect squares between $1$ and $100$ are: $1^2=1, 2^2=4, 3^2=9, 4^2=16, 5^2=25, 6^2=36, 7^2=49, 8^2=64, 9^2=81, 10^2=100$.So,$A = \{1, 4, 9, 16, 25, 36, 49, 64, 81, 100\}$.The number of favorable outcomes is $n(A) = 10$.The probability $P(A)$ is given by $\frac{n(A)}{n(S)} = \frac{10}{100} = \frac{1}{10}$.

$A$ card is drawn from a pack of $100$ cards numbered $1$ to $100$. Find the probability of drawing a number which is a square.
