Question

A card is drawn from a packet of $100$ cards numbered $1$ to $100$. The probability of drawing a number which is a square is:

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

Answer 1

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

Favourable outcomes= $(1,4,9,16,25,36,49,64,81,100)$
number of favourable outcomes =$10$
Total possible outcomes =$100$
Probability = $\frac{10}{100}$ =$\frac{1}{10}$
