# bloc 1x1x2 on corner probability

##### Member
Basically, this is about getting an edge matched with an adjacent corner on a randomly scrambled cube.

I'm usually not so bad at proba, but I get really stick on that one. I don't even know where to start :/ Any ideo to start with will be really apreciated

Yes, I was considering this thread, but I think the problem is way too complex and would have messed up the thread.

I have noticed in my practice that it seems quite common, but not on enough scrambles to have an accurante result (I guess something like 0.4 is a realistic estimation).

The probability thread kinda sucks since it's too flooded with questions like "What's the probability for getting two PLL skips in a row?". I've tried to ask non-trivial questions, but to no avail. :/

What about making a wiki page?

Perhaps a chart of probabilities, along with misc. facts, would be useful.

As for the original question in this thread:

1/24 for a pair to match, 24 possible pairs. So, about 1-(23/24)^24 ≈ 0.64

Ok, I think you took the right direction lucas ! However, pairs are not independant, so your result isn't correct.

Yeah, of course I know that, hence the "about" and squiggle marks. I was posting it because I thought this calculation should have been an obvious first step, but no one has done it in this thread yet.
