How the picker works
Maths Challenge Generator runs entirely in your browser — no servers, no accounts, no data sent anywhere. Each pick uses your browser's built-in cryptographic random-number generator (window.crypto.getRandomValues), which is uniformly distributed across the option pool.
The pool for this picker: 15 hand-picked options. Every option has an equal probability of being selected on any given pick (about 6.67% per option).
Picker-kind picks return a single random option from the pool. If you add your own options, they're weighted equally alongside the built-in set.
If you want a deliberately weighted pick (favouring some options over others), the picker isn't the right tool — try structuring the choice as a wheel with duplicated entries, or split into two picks (category first, then item within category).
