I just had 2 PLL Skips in a row. Is that insane? The odds of this are 1/484 right?

The probability of getting 2 PLL skips in 2 solves is 1/5184. But the probability of getting 2 PLL skips in a row somewhere in your session depends on how many cubes you did.

I've had 3 PLL skips in a row. What are the chances of that?
For the second and third PLL skip, they had the same OLL, although I'm not sure about AUF for any of them. Could you calculate the chances for 3 PLL skips in a row, or the chances for 3 PLL skips in a row getting the same OLL twice in a row?

PLL skip chance: 1/21
same OLL on 2 solves: 1/(57^2)
total probability: 1/30,088,989
you sir, are incredibly lucky :D

Read the second half of his post saying "the probability ... depends on how many cubes you did"
The probability of sitting down with the cube, doing just 3 solves, and having those 3 solves be PLL skips is A LOT less than the probability of doing an average of 100 and having 3 in a row be PLL skips, which in turn is A LOT less than the probability of getting 3 PLL skips in a row at some point during the thousands and thousands of solves you've done in your lifetime.
