if Ethereum is a distributed computing platform

It isn't; it's a replicated/redundant computing platform.

If I make a simple program to get a random number from 1 to 100, or base my program on a randomizer, how can that be repeated in every single node? Shouldn't they give different outputs? How can that be validated?

Let's say I want to make a betting app, based on the random rolling of dice. How can that work?

Can't you grab it out from latest block hash?

You can, if you want the result to be able to be manipulated by miners.

@AlexGR, everything in Ethereum is deterministic. There are no operations that have different results on different nodes. At least if everything works properly. If not then it can fork the chain.
