Question

Cards are marked with no. $2$ to $101$. A card is drawn at random what is the probability that is a perfect cube.

• A. $\frac{1}{100}$
• B. $\frac{2}{100}$
• C. $\frac{3}{100}$
• D. $\frac{4}{100}$

Answer 1

The correct option is C $\frac{3}{100}$

Total cards : $100$ (Numbered from $2$ to $101$)

Total number of cards with cube of a number written over it: $3$ $\to \{8,27,64\}$

Probability of getting a card with cube number written over it: $P=\frac{3}{100}$
