GBM:

Q: What is the probability for a pseudo-random number generator to generate a specific number as his next output?

A: 1 or 0 because you can actually calculate the next number if you have the available information.

Q: What probability do you assign to a specific number as being it's next output if you don't have the information to calculate it?

Replace pseudo-random number generator with dice and repeat.

Even more important, I think, is the realization that, to decide how much you're willing to bet on a specific outcome, all of the following are essentially the same:

• you do have the information to calculate it but haven't calculated it yet
• you don't have the information to calculate it but know how to obtain such information.
• you don't have the information to calculate it

The bottom line is that you don't know what the next value will be, and that's the only thing that matters.
