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 $$.012\cdots9899 \ \to \ .012\cdots98(9+ 8/2)1\ ??$$

revised Determine the $n$th string among those of a given length in alphabetical order starting at a given string and using a given character set?
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.

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.

comment Finding an expression for a joint probability if two random variables have the same distribution function.
@MathDamon - I've added that to the answer.
