Serious question. What if there was someone who was born and wasn't taught any written language or mathematics, but was "measured" to have a high IQ on the basis of those pattern/spatial reasoning. How would this high IQ person be able to answer your proposed question when they couldn't read and had no mathematical background?

It would be rather disingenuous to regard this person as low IQ simply because they hadn't been exposed to language or mathematics.

>>10200656
don't take this post too seriously
OP is insecure about his IQ and is simply resorting to this thread as a method of convincing himself that his IQ is in the high 132s

>>10200656
You don't need any mathematical background to solve the questions. The problem can be explained verbally. The notion of probability in the simple case of a triangle and 3 ants could easily be comprehended by a high IQ person, and they would be able to further extrapolate to 3 dimensional objects with more vertices and edges.

It should also be noted that highly culturally biased tests like Vocabulary and Information (literal trivia, like "Where is Finland?") are more g-loaded and correlate more highly with performance subtests than different performance subtests do with one another.

8\2187 for the cube, am I correct?

Chris langan was able to solve this

Make 3 pairs of squares out of cube each pair has 4 combinations of possibilities so 12 (rotate either square clockwise and counter clockwise).

Make 4 different big rectangles out of cube along each axis of rotation. So that gives you 4 * 3 * 2 (clockwise and counter clockwise). It would be (24 + 12)/3^8

same. Waste of time

i did it but ill never tell the answer because then id reveal my iq. my father believed if the world found out who i really was, theyd reject me. he was CONVINCED that the world was not ready yet. what do you think?

>>10200749
>reduce to 2-D objects
how is this even a measure of g? This was my first thought, its just a bunch of 2-D shapes there's no real "manipulation" of 3-D objects other than deconstructing them.

>>10200634
I can't be bothered with 38, 39, 40.
41 is 3/3486784401
42 is 5/244140625

>>10201167
nice

>>10200749
Each vertex on a cube is an intersection of three lines, meaning there are three potential directions the ants could choose to go.
Seeing the only way the ants can't meet is if they all go in the "same" direction which I'll arbitrarily assign as C, L, R, there's only three potential cases where no two ants will meet, CCC, LLL, RRR.
So, you're wrong.

>>10201211
Nah. With 6 lines you can make a saddle-shaped hamiltonian cycle on the cube which is also solution.
2/729 for the cube, 9/1024 for the octahedron

>>10200749
With 3 squares you count certain vertices twice...

>>10200656
A true perfect genius could conjure up meaning without a need for those things to previously exist. If Newton was immortal he would have done this.

Where did I fuck up? Programmatic solution: https://pastebin.com/ggsyfERT

Variables v1, v2,...,v8 according to pic related. 0 = counter clockwise movement, 1 = clockwise movement, 2 = neither (along z axis).

12 cases where there is no collision: For each pair of opposing sides of the cube, the opposing sides can be 1. Rotaing clockwise, 2. Rotating counter clockwise, 3. One side rotating clockwise and one side rotating clockwise, and 4. Opposite of 3.

These 4 cases apply to the 3 pairs of opposing sides, so 12 cases in total where there is no collision.

1000000000 runs gives 1828705 no collisions. Approximating to 1830000, this gives a probability of 1830000/1000000000 or 183/100000

Statistics is for people with an IQ below 100, so your post is flawed.

>>10200634
Is there a general answer for all the shapes like, number of paths for each ant/number of paths for each ant ^ number of ants?

for example the tetrahedron would be 3/3^4, cube would be 3/3^8?

>>10201188
Everything is a measure of g to a certain extent. Where did you get the idea that only 3d object manipulation is the only thing that's g-loaded? In fact it's less g-loaded than verbal tests. >>10200670

>>10200670
What is g loaded

>>10202287
The extent to which a certain test correlates with g.

>>10202290
What is g

https://en.wikipedia.org/wiki/G_factor_(psychometrics)

>>10202314
So culturally biased tests correlate more with g but then it wouldn't be a fair way to test people who are high IQ but perform badly due to the foreign cultural

>>10202319
Yes, cultural and verbal subtests should be tailored to the person. Most of us would be classified as severely mentally handicapped on an untranslated mandarin test for instance.

>>10202324
To add: But in the event where everyone tested is from the same culture and has the same native language, cultural and verbal tests are very strong measures of general intelligence, even more so than nonverbal tests.

>>10202327
Despite being in the west, we aren't actually doing the same things as normies do so even then you can't say we come from the same culture as normies

>>10202363
major cope

>>10202368
I don't have friends. I never go to a bar. I never open Instagram or reality tv or Snapchat. I don't read newspapers.
I didn't share the culture of normies

>>10201962
That's basically it, but there are a few more special paths that can be taken.
For example, with a cube all the top ants could move clockwise and all the bottom ants could move counter clockwise. One ant could descend and the next ant along could ascend, while the rest rotate.

IQ is a fucking spook gaylords, meditate and control every function, the brain has an endless means of reproducing itself. Same way cells divide.

>>10200634
200IQ+ there is no right answer

Physics student with poor background in probability:

For a tetrahedron:
There is a 1/3 chance that an ant will travel down a side. A side is attached to 2 vertices, meaning there is a (1/3)^2 chance of an encounter. We want to know the chance that there will be no encounter, so P_side=8/9 for each side. With 6 total sides, P_total =(8/9)^6=0.49

Similarly for a cube:
P_total =(8/9)^6=0.24

If each ant starts to move at the same time, then we can assume each event is independent thus validating that there is an 8/9 chance of no encounter for vertices attached to 3 sides.

>>10204310
>Similarly for a cube:
>P_total =(8/9)^12=0.24

fixed (cube has 12 sides)

>>10200634
I haven't yet solved it but my theory is:
You can divide each polyhedron into cycles and dots
each cycle can be traversed in two ways
a point can only be traversed in one way
The number of edges at each vertex to the power of the number of vertices in a polyhedron corresponds to the sample space
the cycles that divide a polyhedron are planar
All vertices are part of a cycle or a point
Cycles do not share any vertex
cycles divide the polyhedra into two subgraphs that are themselves with cyclse
cycles cover a number of adjacent polygons
In other words you can construct a cycle from adjacent polygons
If the cycle encompasses certain polygons then the polygons could form cycles inside that cycle such that no polygon in the encompassed cycle shares a polygon at the border of the encompassing cycle or another encompassed cycle, nor are their polygons neighbors of each other
arrangemnets of polygons are equivalent if they cut the graph in the same way
each individual cut has two such arrangements
One can construct a graph between the faces, so that edges that move from same color to same color can be labelled and same and the other as different.
Two vertices that are connected by a series of Same-labelled edges that share connections with a vertex will be connected with that vertex in the same way (say both same or both different)
The minimal description of such graph is a list of same-edges connected to a unique vertex (the rest of properties can be inferred from this)
but from then-on I'm stuck... Anyone could give me a hint without spoiling me?

Never mind, just realized the problem asks about multiple rotations and not just one. Considering they don't bother specifying the rules on the number of rotations that need to be made, this problem is not able to be solved. And even if they did specify that an ant has to make x steps before returning, the problem would be able to be solved analytically.
