• A. $\frac{1}{10}$
• B. $\frac{9}{100}$
• C. $\frac{1}{100}$
• D. $\frac{2}{100}$

Answer 1

The correct option is A $\frac{1}{10}$

Possible outcomes on drwaing a card are numbers from $1$ to $100$

Out of the possible outcomes, numbers which are a square are $1,4,9,16,25,36,49,64,81$ and $100$.

Probability $=$ Favourable Outcomes $÷$ Total Outcomes $=\frac{10}{100}=\frac{1}{10}$
