Oh! Oh! I know this one
Took forever to find it on stackoverflow

So you want a bell curve with 0.5 most often, and near 0 or 1 to be rarer
This is how
(RND()+RND())/2
for a little bit of focus on 0.5
(RND()+RND()+RND())/3
for more focus on 0.5
(RND()+RND()+RND()+RND())/4
for more focus on 0.5 and near 1 or 0 to be way way more rare
...and so on
