Shell description
The dextral or sinistral shell is ovate-conic, and colored glossy yellow, green, olive or chestnut; often banded with green or chestnut. The shell has 6 1⁄4 whorls. The color pattern is extremely variable.[2]
The height of the shell is 19.0 mm. The width of the shell is 10.0 mm.[2]
gollark: I assume you're doing binomial distributions if whatever A-level spec you do is similar to mine, which it probably is, in which case I don't think they cover anything more advanced than trial and error/look at a table for that. Although it's probably <=/>= instead of = 0.02, as there's no guarantee that there is any x satisfying the = version.
gollark: It *also* matters how it's distributed.
gollark: I'm pretty sure you need information about what "X" is there.
gollark: I suppose you could just work out how many possible 50-move sequences exist somehow. There's definitely more than you could tractably store, at least.
gollark: Is it two images for the real and imaginary part or what?
