Probability of Sum in 3-Side Die: Answers Needed!

[encapuchado]

Hi,

I've looking in the internet but I can't find a straight answer.

The problem is this:

Suppose we have a 3-side die (faces marked 0, 1, and 2).

Are there general formulas to answer questions such as:

a) "After throwing the die 100 times, get the probability of the sum being 120"?
b) "After throwing the die 100 times, get the probability of the sum being greater or equal to 120"?

Any help is appreciated.


P.S. This is not homework, I'm too old to be a student ;-)

Neither do I. What I can tell you is, "yes, there are such general formulas."

Yeah, I also found some formulas in the wiki http://en.wikipedia.org/wiki/Dice#Probability. However, I thought the problem were easier and with a nice formula like the binomial distribution.
