MCQ
Choose the correct answer from the given four options : One ticket is drawn at random from a bag containing tickets numbered $1$ to $40$. The probability that the selected ticket has a number which is a multiple of $5$ is :
  • ✓
    $\frac{1}{5}$
  • B
    $\frac{3}{5}$
  • C
    $\frac{4}{5}$
  • D
    $\frac{1}{3}$
✓

Answer

Correct option: A.
$\frac{1}{5}$
Number of total outcomes $= 40$
Multiples of $5$ between $1$ to $40 = \{5, 10, 15, 20, 25, 30, 35, 40\}$
$\therefore$ Total number of possible outcomes $= 8$
$\therefore\ \ \text{Reqired probability}=\frac{8}{40}=\frac{1}{5}$
