Thanks.

Here is a statement from a textbook that I’m referring to:
From a set containing $ l$ things of one kind, $ m$ things of a different kind, $ n$ things of a third kind and so on, the number of ways of choosing $ r$ things out of this set of objects is the coefficient of $ x^r$ in the expansion of $ $ (1+x+x^2+x^3+…+x^l)(1+x+x^2+x^3+…+x^m)(1+x+x^2+x^3+…+x^n).$ $
Can someone please explain the intuition behind this? How can it be derived?
I know that Africa is very large and very diverse, a continent and not anything like a single country, and cell phone hardware is presumably not uniform.
However, if it is known, what kind of font(s) would be optimal for ebooks intended for consumption on smartphones in Africa?

In D&D 5e, the detect evil and good spell states that:
For the duration, you know if there is an aberration, celestial, elemental, fey, fiend, or undead within 30 feet of you, as well as where the creature is located. Similarly, you know if there is a place or object within 30 feet of you that has been magically consecrated or desecrated.
To me, it’s unclear whether, if the caster detected some consecrated ground, it would be possible for them to mistake it for desecrated? Or vice versa? Do they just know that this ground has been touched by the gods, or specifically whether there were good or evil ones?
I’m not asking with regards to a specific situation that happened in play; I’m just curious how it should go as intended by the game writers.
I have a problem with my Ubuntu background. It seems to get some kind of pixelized. I searched the internet but couldn’t find any solution. My background is the default background from Ubuntu 19.04.
Here is my desktop
The problem usually occurs after I put my notebook in hibernation mode. I recently installed bumblebee with nvidia drivers. Bumblebee is from the official repos and the drivers from the nvidia ppa.
I’m looking forward to your answers. Thank you!
