Question

You have an eight-faced die. In this die, one of the faces contains 1, two faces contain 2, three faces contain 3 and other faces contain a 4 and a 5 respectively. What is the probability of getting a 3 when the die is rolled? (All outcomes are equally likely).

• A. $\frac{1}{2}$
• B. $\frac{3}{8}$
• C. $\frac{1}{4}$
• D. $\frac{1}{8}$

Answer 1

The correct option is B

$\frac{3}{8}$

Probability of an event

= $\frac{\text{Number of desired outcomes}}{\text{Total number of outcomes of the experiment}}$

Total number of outcomes = 8

Number of desired outcomes i.e. getting a 3 = 3(3 faces contain the number 3)

Therefore, Probability of getting a three when the die is rolled is $\frac{3}{8}$.
