The One-Answer Question Thread [closed]

[Moops]

Does anybody have any idea of how Feliks is doing his edge pairing here? I can see that it's freeslice but I'm having trouble seeing whether he's pairing wing pieces with center edges or building whole tredges one at a time. Very fast with lots of rotations so it's hard to follow >_>

I wouldn't say they suck, just aren't quite as good. Can you order Maru lube anywhere?

What are the chances of three PLL skips in a row?

What are the chances of three PLL skips in a row?

The chances of getting 3 PLL skips on your next 3 solves is 1/72*72*72, or 1/373248. But, of course, on any 3 consecutive solves, the chances are much more likely, because you've done more than 3 solves in your life.

What are the chances of three PLL skips in a row?

1/72.

Because a PLL skip has a 1/72 chance of happening. In my opinion, those who say it's 1/373248 are wrong. My mentality on it is that just because you've already had a PLL skip doesn't mean your chances will be any lower on your next solve.

Because really, does your cube know that you just got a PLL skip? Does it want to make sure you won't get 2 or 3 in a row? No, so the fact that you just got 1 or 2 in a row doesn't affect the chances of getting another one.

The probability of you getting a PLL on your next 3 solves is 1/373248.

 

[cubernya]

The probability of you getting a PLL on all of your next 3 solves is 1/373248.

[BlueDevil]

The probability on any given solve is 1/72, regardless of what has previously happened. But getting it twice in a row is 1/5184.

Think about this, the odds of flipping tails twice in a row on a coin is not 1/2. It's 1/4, because you need it to happen twice in a row. Because there are four possible outcomes HH, HT, TH, and TT. Only one of the four of those is what you want, so 1/4.

Ok, the probability as stated of any specific 3 solves chosen at random being a PLL skip will be

This is a terrible way of thinking of it, however. Try this:

Is Traxxas diff. oil good?

its good. its bassicaly the same thing as lubix. and cheaper.

 

[Yuxuibbs]

Is Traxxas diff. oil good?

Yes. It's basically a cheap alternative to Lubix and some people can't tell the difference between traxxas and lubix. Make sure it's 30-50k wt.

I noticed this today, and I noticed that there aren't any cubers anywhere near me. Is this map updated fairly frequently (like, do most cubers register on it), or is it sort of outdated?

Those only include the people that have a cubingusa account. It is the same thing with state rankings.

Ok, but are many cubers registered? I registered a long time ago, but I'd like to know if it's a "common" thing to do, and if the map can be taken accurately.
