Question

A dice is thrown once. Find the probability of getting a factor of 6.

• A. 1/3
• B. 1
• C. 2/3
• D. 2/5

Answer 1

The correct option is C

2/3

The sample space is S = {1, 2, 3, 4, 5, 6}; n(S) = 6

Let E be the event of getting a factor of 6.

E = {1, 2, 3, 6}; n(E) = 4

Therefore P(E) = $\frac{n\left(E\right)}{n\left(S\right)}$= $\frac{4}{6}$= $\frac{2}{3}$
