Question

Twelve sides dice are used in adventure games. They are marked with the numbers $1$ to $12$. The score is the upper most face If this disc is thrown what is the probability that the score is a factor of $12$?

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

Answer 1

The correct option is C $\frac{1}{2}$

There are $6$ Factors of $12$ within the numbers $1$ to $12$ - $1,2,3,4,6,12$
Thus, out of the $12$ possible outcomes, $6$ are factors of $12$.
Thus, the probability that the score is a factor of $12$ = $\frac{6}{12}=\frac{1}{2}$
