Yep, the sum of six Math.random() will start to look a bit like a normal distribution, while Math.random()*6 will stay flat.

Even crazier: the sum of six (Math.random()>.5)?0:1 will also look a bit like a normal distribution, rather than just 0 50% of the time and 6 50% of the time.

Central Limit Theorem eats distributions of all shapes and sizes and shits gaussians. That's why you see normal distributions everywhere.

Yeah, it will biased towards the center of the range rather than uniformly distributed
