(6! x 3!)/9!
=
(720 x 6)/362880
=
4320/362880
=
0.0119
which is 1/84

You rank amateurs need the practice. I just want to say that I think the test is clever and cute. Maybe it could be improved upon by showing the user just a couple of pictures and asking the user to select from a multiple-choice list to identify them. Kitten, apple, monkey, whatever. Monkeys are always good. Oh yes, the monkeys. Sure, monkeys in a barrel sounds like a lot of fun until UPS delivers the package and a bunch of dead monkeys fall out.

That's "how many combinations of 3 picks are there in 9 choices without being able to select one thing twice" in combinatorial statistics and that gives you 84 choices. Its not great and I'm working on ways to make it better. Thanks for the write-up Michael... But why is my name "Oli" and not Oli? I’m glad you’re having so much fun over my maths =)
