math – What is the probability of randomly getting a 12 word seed phrase with the same word repeated 12 times? – Beragampengetahuan

That’s not correct.

Remember that the last word has a checksum for the other 11, which means that not every word of the 2048 will work.

Actually, only 190 words do the trick, which means there are only 190 phrases possible in a universe of 2048^12 possible phrases, so the the probability is 190/2048^12
