Question

There are $30$ tickets numbered from $1$ to $30$ in a box. A ticket is drawn at random. What is the probability that the ticket drawn bears a number which is a perfect square?

• A. $\frac{1}{4}$
• B. $\frac{1}{3}$
• C. $\frac{1}{6}$
• D. $\frac{1}{8}$

Answer 1

The correct option is C $\frac{1}{6}$

Total number of outcomes $=30$
Favourable outcomes (a number which is a perfect square) $=\{1,4,9,16,25\}$
Probability $=\frac{5}{30}=\frac{1}{6}$
