Mass points question

Today at 2:27 AM
So I was working my way through mass points, and I found a rule that basically says:

"If transversal line EF crosses cevian AD in triangle ABC, you must split mass A into Mass ab and Mass ac. Could someone explain to me why this makes sense/why we couldn't just use mass A?

What's the chance that two AoPS accounts generate with the same icon?

N Today at 2:21 AM by martianrunner
So I've been wondering how many possible "icons" can be generated when you first create an account. By "icon" I mean the stack of cubes as the first profile picture before changing it.

I don't know a lot about how AoPS icons generate, so I have a few questions:
- Do the colors on AoPS icons generate through a preset of colors or the RGB (red, green, blue in hexadecimal form) scale? If it generates through the RGB scale, then there may be greater than $256^3 = 16777216$ different icons.
- Do the arrangements of the stacks of blocks in the icon change with each account? If so, I think we can calculate this through considering each stack of blocks independently.

A store sells a strawberry flavoured candy for 1 dollar each. The store offers a promo where every 4 candy wrappers can be exchanged for one candy. If there is no limit to how many times you can exchange candy wrappers for candies, what is the maximum number of candies I can obtain with 100 dollars?
