Pick 2 points P, Q, uniformly at random in the interior of a sphere.

The line containing P and Q intersects the surface of the sphere at 2 other points, A, B.

What is the probability that the angle ∠ACB, where C is the centre of the sphere, is greater than 120°?

Right, so this isn't like Bertrand's paradox where the result depends upon the specific method of 'choosing random points' - right?

The correct answer is 37/64.

Congratulations to the voter who got it right!

Yes, an explanation it you have time please.
I think I was able to figure out the geometry of the portion of the sphere that would contain valid A and B points. But got stuck yesterday figuring out valid P and Q to match.

The short answer is that the CDF for the angle between A and B, call it γ, is:

CDF(γ) = (1/8)(1 - cos γ)^3

So the result is:

CDF(π) - CDF(2π/3) = 1 - 27/64 = 37/64

I'm not sure what the nicest way is to prove the CDF. You can express the dot product between A and B in terms of the coordinates of P and Q, rotate P to lie on the +ve z-axis (while weighting the result with 4π z_P^2) and rotate Q to lie in the xz plane with +ve x (while weighting the result by 2π x_Q), so after dividing by the volumes of both unit balls you end up with the integral of:

(9/2) z_P^2 x_Q

over the range:

0 < z_P < 1
-1 < z_Q < 1
0 < x_Q < sqrt(1 - z_Q^2)

with a further inequality on the dot product between A and B:

2 x_Q^2 z_P^2 / (x_Q^2 + (z_P - z_Q)^2) - 1

This can be turned into another inequality on x_Q that only applies for part of the domain of z_P, and then it's a matter of splitting all the domains into individual pieces where one or the other applies, which can then be integrated analytically.

Thank you for the short answer and a potential proof Greg.
I'd already concluded that I was off track in my reasoning, especially after seeing @FenTiger 's reply.
My maths skills are out of practice but I loosely follow the proof. Not knowing how to fix P and Q was what I decided was wrong and hadn't figured out how to correct.

Here is an alternative proof for people who are comfortable with Jacobian matrices and determinants.

Though I did this in Mathematica and it involves a 6 x 6 determinant, there are a lot of zeroes in that matrix and it could probably be done with pen and paper without too much trouble.

The Mathematica code here defines a point on a sphere in standard polar coordinates θ, φ, defines two points A and B with their individual pairs of polar coordinates, then two points P and Q on the line segment between A and B, with parameters λ, μ for how far each of them is along the line segment.

We then compute the Jacobian matrix of partial derivatives for the pair (P,Q) with respect to the six parameters, set A and B to lie on the equator at θ=π/2, while A is at φ=0 and B is at φ = γ.

The determinant of the Jacobian matrix is:

(λ-μ)^2 (cos(γ)-1)^2

We find the probability density function for γ by integrating over λ and μ from 0 to 1, multiplying by 4π (for A moving over the whole sphere), 2π sin(γ) (for B rotating around A while staying at an angle of γ), 1/2 (to avoid double counting configurations where A and B are just swapped), and dividing by (4π/3)^2, for the total volumes P and Q are selected from.

The result is the probability density function:

PDF(γ) = (3/8) (cos(γ)-1)^2 sin(γ)

which corresponds to the cumulative distribution function:

CDF(γ) = (1/8) (1-cos(γ))^3

from which we obtain the result:

CDF(π) - CDF(2π/3) = 37/64

Wir setzen uns erfolgreich für Tempo 30 und Verkehrssicherheit ein. Jetzt ganz frisch und neu aus dem Schilderwerk gibt es T30 auch auf dem letzten Stück Reichenbachstraße, einem wichtigen Schulweg.
in reply to ADFC Dresden

Das Bild zeigt eine ruhige Straße in einer Stadt, vermutlich in Deutschland, mit einer Fahrbahn für Radfahrer und einigen Parkplätzen für Autos. Auf der rechten Seite der Straße steht ein Straßenschild mit der Aufschrift "Hochschulstr." und ein weiteres Schild mit der Aufschrift "Straßen-schäden" und einer Geschwindigkeitsbegrenzung von 30 km/h. Ein Radfahrer in einem weißen T-Shirt und dunklen Hosen fährt auf der rechten Fahrbahnseite entlang. Die Straße ist von Bäumen gesäumt, die im Herbst ihre Blätter verlieren, was auf den Herbst hinweist. Ein weiteres Fahrrad mit einem schwarzen Rucksack lehnt an einem Schildpfosten. Im Hintergrund sind mehrere Gebäude zu sehen, darunter ein Mehrgeschossgebäude. Die Szene wirkt ruhig und friedlich, mit einem gepflegten Grünflächenbereich auf der linken Seite.

So, I was about to review a PR to add GoToSocial support to @IceCubesApp, but I guess I won't do it then.

This is completely baffling to have such "code of conduct" at the age of AI.
I won't waste any second of my brain cycle, or my AI cycle, on their network.

Good riddance.

do you know if there is a way to easily migrate a gts instance to a snac instance using the same domain, and the other way around? There is a think with someone keeps that need to be exported or something similar, that I don't know if that's possible.
in reply to raspbeguy

Same domain is not possible (or, more accurately, you risk federation problems related to keys). However, you can create a subdomain (e.g., snac.example.com) and move to it.

HONESTY.....

Chancellor Merz:

"We are currently unable to exert sufficient pressure on Putin to end this war. We are dependent on American help.

So what concerns me and, I will admit, also bothers me, is the fact that we as Europeans are currently not playing the role in the world that we actually want to play and that we should play in order to ensure that our interests are adequately protected."

The image features a sheep standing on a grassy hill during what appears to be early morning or late evening, as indicated by the soft, diffused light and the pastel colors in the sky. The sheep has a thick, woolly coat that is predominantly white with some darker patches, and it is looking directly at the camera. The background shows a misty landscape with rolling hills and valleys, creating a serene and expansive view. The sky is a gradient of colors, transitioning from a light blue at the top to soft pinks and oranges near the horizon, suggesting the presence of a sunrise or sunset. The overall atmosphere is calm and tranquil, with the sheep as the focal point against the vast, mist-covered landscape.
