- complement: Everything except the event: the chance something does not happen is 1 minus the chance it does.
- independent: Two events are independent when one happening doesn't change the chance of the other, like two separate coin flips.
- mutually exclusive: Events that can't both happen at once, like a die showing 2 and showing 5. Their chances simply add.
- probability: How likely something is, from 0 (never) to 1 (certain).
