If ARAM is "random" then how do I keep getting the same champ twice in a row?

Say I own 60 champs. That means the odds of getting the same one twice in a row is 1/60 multiplied by 1/60 which is 1/3600. Yet this happens alllll the time. The algorithm is terrible. Not even close to random.

When you get Trynd. Then dodge and get Trynd again.

It isn't really 1/3600 because there are several things that need to be considered:

  1. The champions you own.
  2. The champions you don't own.
  3. The champions your teammates and the enemy team own or don't own.
  4. Which free week champions are available to play (because you can roll them in ARAM).

I'm sure the code for the ARAM algorithm is pretty crazy, but because of all the external factors that you can't control, it won't ever truly be random.

Kinda the same case here, not the "same champ twice in a row", but I've noticed that each week, I tend to get the same picks a lot more times than usual, mostly the free champions given for said week (I own every single champion if you need to know)

Trust me. Getting a Morgana on the enemy team 5 times in a row isn't fun.

I keep on getting aatrox in ARAM not matter what the free champions are.

Google Random and find out what Random really means. You could give the same champ 5 times in a row and technically it's still Random. :)

You have 1/3600 chances of getting x champion twice in a row, but 1/60 chances to get the same champion twice in a row. And you can RR, trade, or just accept that it happens in 1/60 or 1/3600 (depending on how you look at it) scenarios.
