Problem

When a fair six-sided dice is tossed on a table top, the bottom face cannot be seen. What is the probability that the product of the faces that can be seen is divisible by $6$?

$\textbf{(A)}\ 1/3\qquad\textbf{(B)}\ 1/2\qquad\textbf{(C)}\ 2/3\qquad\textbf{(D)}\ 5/6\qquad\textbf{(E)}\ 1$

Solution

All the possibilities where $6$ is on any of the five sides is always divisible by six, and $1 \times 2 \times 3 \times 4 \times 5$ is divisible by $6$ since $2 \times 3 = 6$. So, the answer is $\boxed{\textbf{(E)}\ 1}$ because the outcome is always divisible by $6$.
