FAQ

How does weighted random selection work?

Each item's chance of being picked is proportional to its weight. If item A has weight 2 and item B has weight 8, B is 4 times more likely to be selected than A.

Can I use decimal weights?

Yes, you can use any positive number as a weight, including decimals. The generator normalizes all weights automatically.

Is the result truly random?

Yes. The generator uses a cryptographically secure random number generator to ensure fair and unpredictable results every time.
