I suppose finding two "aa" in 256 is just as likely as finding one "aa" in 256. After all, hashes don’t "understand" that... lol.
No, but finding one “aa” after you found an “aa” is just as likely as finding “aa” if you didn’t find any “aa”
2 "aa" is about 0.0015/256, 1 "aa" is about 1/256.
and finding "aa" twice in 256 samples is much rarer than finding just one. But, as you correctly pointed out earlier, hashes themselves don’t "care". each search is statistically fair and unaffected by prior results.
Probability paradoxes, right?
