1/162whats the probability of getting a 2x2 LL skip?
Thanks for the answers!
I'm really starting to enjoy this thread. ;D
What's the probability of having sune as OLL + A perm as pll?
On the 5x5x5, the probability that all the edges would be tripled up correctly is:
1/24! = 1/620,448,401,733,239,439,360,000
For the 4x4x4, the probability of all edges being paired up correctly is:
1/23!! (where !! is the double factorial operator), or 1/(23*21*19*17*15*13*11*9*7*5*3*1) = 1/316,234,143,225.
whats the probability of getting a pyraminx LL skip?
what is the probability of getting an x-cross (unintentionally) after doing a regular cross?
what are the probabilities of the fewest amount of misoriented edges [R,L,U,D,F2,B2] in all orientations as opposed to in a fixed orientation?
bad edges count
0 103741
2 6500978
4 35204527
6 26728948
8 2411347
10 13658
12 1
Using GAP, I've come up with the following distribution:
Note that for 12 bad edges, every edge must be in its proper inner layer. If an edge is in the wrong inner layer, there will be some cube orientation that will make it oriented. Hence, the above distribution has only 1 case with 12 bad edges.
Edges can also be scrambled, but only within their respective layers (E,M,S). So actually 13824 possible edge configurations.So basically the only position where all edges are bad in any orientation is superflip (corners could be scrambled of course)
Fairly simple just to think through logically.Last 2 Center skip on 5x5?
Just as kinch2002 said, it's 1/4900.Last 2 Center skip on 5x5?
No more than 3 wing edges are solved, no more than 3 corners are in their correct locations, and no more than 4 middle edges are in their correct locations.
Assuming you're interested in the probability for the color neutral solving...Skip on Guimond 1st step (3/4 of a face with opposite colours)
[post]152726[/post]and Ortega step 1 (face)?
To give a comparison, the chance of a LL skip with no partial edge control, and with the possibility of AUF, is
1 / 15552
I thought it was pretty neat.
