Question

When a certain biased die is rolled, a particular face occurs with probability $\frac{1}{6}-x$ and its opposite face occurs with probability $\frac{1}{6}+x$. All other faces occur with probability $\frac{1}{6}$. Note that opposite faces sum to 7 in any die. If $0

Select the correct option:

A

$\frac{1}{16}$

B

$\frac{1}{8}$

C

$\frac{1}{9}$

D

$\frac{1}{12}$
