The hardest logic puzzle ever

Wow this is seriously the most crazy logic puzzle ever. If you can solve it on your own, you are really pretty damn amazing.
I'm reading the solution and I'm already taking ages to even understand it lol.

WARNING - this is really mindf-k to the max! Don't embark on it if you don't want to kill 213987 of your brain cells.

The Puzzle:There are 3 people, A, B and C. One of them always tells the truth, one of them always lies, and one of them always randomly decides to tell the truth or lie.
Your task is to ask 3 yes-no questions, each question has to be directed to only one person, and figure out who is which.

Some clarifications:
- They know each other's roles
- You can ask one person more than one question (e.g. all 3 questions can be directed at A)
- Whether the Random person speaks truly or not should be thought of as depending on the flip of a coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.
- Your question has to have a yes-no answer. (E.g. no 'maybes', paradoxes, etc)






If you solve it let me know what your 3 questions are! :D Contact me for any further clarifications too.
