What is the probability that the total of the two dice will add up to 7 or 11?
2/9
So, P(sum of 7 or 11) = 2/9.
Can dice have more than 6 sides?
More Than 6 10-sided dice come in the shape of pentagonal trapezohedra; this shape resembles two pentagonal pyramids that have been fused at their bases in such a way that the faces of one pyramid line up with the edges of the other. These dice are usually used to derive percentiles in role-playing games.
What is opposite 3 on a dice?
6
Thus, there is only one number that could be opposite ‘3’ i.e. ‘6’. So, ‘6’ is the opposite ‘3’ in the given dice. Hence, the correct answer is “6”.
