MCQ

 A die is rolled. What is the probability that an even number is obtained?

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

Answer

  1. $\frac{1}{2}$

Solution:

 

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 

$=\frac{3}{6}=\frac{1}{2}$
