Question

What is the probability of rolling a total of 20 with 10 dice? More generally, what is the probability of rolling x with n dice?

Answer 1

Clarification: Dice = Standard 6-sided die with numbers 1-6

Answer 2

for n dice the number of ways in which one can roll x
is given by the coefficint of a^x
in (a+a^2+a^3+a^4+a^5+a^6)^n
hence the required prob ca be calculated by dividing the result by 6^n

Answer 3

I'm sorry, I didn't quite get that. Could you please do an example?
