I must have made some mistakes in calculating the following outcomes because my numerator is more than 144 when you add them all up: 2 - 2/144 3...

Since I'm not completely confident I wouldn't fudge one of the small calculations along the way (or even set them up properly), do you think there...

Is there someone with a bit of a physics background who could lend some insight into this problem or evaluate the approach I took in the previous...

This problem seems to want you to use Archimedes' Principle. Since the barrels will be floating, I reasoned that the weight of the displaced water...

Forever sounds daunting, but I would imagine that you're alluding to a converging infinite series.

You are correct! I found your description very helpful. The closer/farther part made the problem click in my head. After finding the solution using...

Agreed. Could anyone enlighten this thread's participants about the easiest way to eliminate the duplicates from the count?

So, is the probability of making a point on the first throw 1 - 7/72 - 2/72 = .875% ?? If so, how does one calculate the probability of ultimately...

How is it possible to deduce the shape of the object without knowing what the object is to begin with?

Is the question how many times the ten lines that were produced from ten surfaces can intersect one another? If so, I would imagine that the answer...

There definitely seem to be 10 distinct groupings of 3 dots comprised of 10 distinct lines...but is that really what the question is asking for?

Great reasoning. How would you answer this one: Six dots are marked on a flat surface so that no more than two at a time may be connected by any...

The use of the word "cubes" in the question is kinda throwing me off. A cube by definition is symmetrical and comprised of six equal squares and it's...

Does everyone agree with this solution or have the same approach and way of explaining the problem?

If a diagonal is drawn across each side of a cube from one corner to another, then how many distinct patterns are possible? For a distinct pattern...

I get that the second and third are related and the fourth and fifth are related. So, I'm guessing the sixth, unknown shape will resemble the first...

Well, the odds of getting a point on the first throw appear to be 7/72 since there's a 1/12 chance of getting a 13 (12/144) and a (2/144) chance of...

Yes, this somehow is supposed to make a 3-D object. Do we know what the object will look like once constructed?

You could get the second piece from the first by simply moving that little piece on the first piece to the right to make it a square and then...

Several identical cubes are fused to form a solid object. Given the following five views of such an object, draw the sixth.

Does that take into account the probability of drawing again (potentially infinitely) if you don't win on the first try?

Maybe the question is just flawed. Why would someone pick the one single-digit quantile without an official name? The answer is definitely related to...

It's definitely a legitimate question. All of the other analogies in the group I saw online made sense and had one perfect answer...except this one.

Did anyone get more than 20 distinct patterns or less than 20 distinct patterns for this problem?

There's just something slightly unsatisfying about that answer. I feel like nonile is more of a neologism than is warranted by the question and that...

I, indeed, came up with nonile too, but I didn't see nonile in any statistics book and I've taken many statistics courses. Still, I suppose that's...
