Ahhh, 345 posts into the debate, you *finally* review the math! Clever boy, aren't you?!
Yes, the calculations are for the probability of *sequencing*; the sequencing of "random" letters typed into words, the sequencing of genetic DNA programming instructions into viable life forms, the sequencing of numbers into a winning lottery ticket...the sequencing for anything and everything based upon aided or unaided (specifically) processes.
In relation to this thread, the unaided sequencing of billions of genetic programming instructions into viable DNA might, if you continue to become more clever, begin to slowly intrigue you.
I hold out such hope for you, at the very least.
