MCQ
An unbiased die is thrown once. The probability of getting a composite number is :
  • A
    $\frac{2}{3}$
  • B
    $\frac{2}{5}$
  • C
    $\frac{1}{2}$
  • ✓
    $\frac{1}{3}$
✓

Answer

Correct option: D.
$\frac{1}{3}$
Number of composite numbers on a dice $= \{4, 6\} = 2$
Number of possible outcomes $= 2$
Number of Total outcomes $= 6$
$\therefore$ Required Probability $=\frac{2}{6}=\frac{1}{3}$
