Question

A single 6-sided die is rolled. What is the probability of getting a 2 or 5?

• A. 1/3
• B. 2/5
• C. 1/2
• D. 3/5

Answer 1

The correct option is A

1/3

The sample space is S = {1, 2, 3, 4, 5, 6}

n(S) = 6

P(2) = $\frac{1}{6}$

P(5) = $\frac{1}{6}$

P(2 or 5) = P(2) + P(5)

= $\frac{1}{6}$ + $\frac{1}{6}$

= $\frac{2}{6}$

= $\frac{1}{3}$
