Dice probability problem

Let a dice with m faces, and on each faces is inscribed a different number from 1 to m, be rolled n times, what are the probabilities of a number k to accur if we add every number shown on the dices?

Hi Gabrielius, This problem might need more constraints for a SAT/ACT math. It can be solved as a generalized problem. However, let me show you 3 examples for you to see the different nature of each. 1. A 6-face dice with numbers 1 to 6 on each face. For n times rolls, what is the probability of a 5 to occur (5 as the sum of total n rolls)? 2. A 99-face dice with numbers 1 to 99 on each face. For n times rolls, what is the probability of a 36 to occur (36 as the sum of total n rolls)? 3. A 10-face dice with numbers 1-10 on each face. For n times rolls, what is the probability of a 36 to occur (36 as the sum of total n rolls)?

Just sayin'. One of the cubes is a "die", the plural of die is "dice".

To determine a probabiity the total number of outcomes must be know.

If an"m" cube is rolled "n" times then the sum (as stated in the problem) ranges from n(1) to n(m).

No defined total number of out comes exists. The problem is inane. No specific not general probabiliyt can be deteremined.
