# The 20-Flip Binomial Distribution a.k.a. Luck Test

Their result for The 20-Flip Binomial Distribution a.k.a. Luck Test ...

## 8 Flips The Same

While writing this test, I too flipped 20 coins.  You matched my flips on 8 of them. Math, if it can be trusted, says you'd match me on around 10 of them, give or take.  In fact, about half of all test takers should match me on 9, 10 or 11 flips.  Fewer than 1 in a million takers should match me on 0.  If this test engine is to be trusted, and no one cheats on my test, the graph of matches below should approximate a bell curve.  (If you're one of the first takers, have mercy.)

I once heard that humans are more likely to pick 3's and 7's as digits when assigning random numbers.  Do the distribution graphs below support that? I'll check back tomorrow.

Thanks.
