MCQ
A number is selected at random from $1$ to $75$. The probability that it is a perfect square is :
  • ✓
    $\frac{8}{75}$
  • B
    $\frac{6}{75}$
  • C
    $\frac{4}{75}$
  • D
    $\frac{10}{75}$
✓

Answer

Correct option: A.
$\frac{8}{75}$
Number of possible outcomes $= \{1, 4, 9, 16, 25, 36, 49, 64\} = 8$
Number of Total outcomes $= 75$
$\therefore$ Probability (of getting a perfect square) $=\frac{8}{75}$
