MCQ
A die is rolled. What is the probability that an even number is obtained?
  • ✓
    $\frac{1}{2}$
  • B
    $\frac{2}{3}$
  • C
    $\frac{1}{4}$
  • D
    $\frac{3}{4}$
✓

Answer

Correct option: A.
$\frac{1}{2}$
When a die is rolled, total number of outcomes $= 6 (1, 2, 3, 4, 5, 6)$
Total even number $= 3 (2, 4, 6)$
So, the probability that an even number is obtained
$=\frac{3}{6}$
$=\frac{1}{2}$
