comment Decimal binary sequences that cannot be greater than $1$
So, for example, it's $$.(0)(1)(2)\cdots(98)(99)\ \to \ .(0)(1)(2)\cdots(98+98/2)(1)$$ and not $$.012\cdots9899 \ \to \ .012\cdots98(9+ 8/2)1\ ??$$

comment counting the good numbers
This is a computer programming question. Write a program that checks the three conditions for each integer between A and B (inclusive). The details depend heavily upon your choice of programming language; e.g., upon the available built-in functions.

Clarify the presumed meaning; add relevant tags.

comment Help applying Bayes' Law
You're welcome. Note: this solution assumes that instead of "76% of the time we do not need to go to m3, we found it in m2", you really meant "76% of the time we do not need to go to m3, we found it in m2 or in m1". Since this answer has been accepted, I presume that it's the value given by your problem-source.

I'm assuming that instead of "76% of the time we do not need to go to m3, we found it in m2", you really meant "76% of the time we do not need to go to m3, we found it in m2 or in m1". Also, what does the problem-source say is the correct answer?

comment What does it really mean when we say that the probability of something is zero?
@krb686 - "How so?": The computable reals in any interval form a null set (i.e., whose Lebesgue measure is zero). This is a mathematical issue, not a physical one.

@MathDamon - I've added that to the answer.

Indeed, if X has a continuous distribution on a real interval then ℙ( "X is computable")=0.
