Question

A die is rolled. What is the probability that the number appearing on upper face is less than 3?
$\left[1\right]$

1. $\frac{1}{6}$
2. $\frac{1}{3}$
3. $\frac{1}{2}$
4. 0

Answer 1

Solution:
Sample Space = {1, 2, 3, 4, 5, 6}
No of favourable outcomes = 2
Total Number of outcomes = 6

Probability =$\frac{Numberoffavourableoutcomes}{Totalnumberofoutcomes}=\frac{1}{3}$

Hence, correct answer is option 2.
