Probability Scale



The chances of any event can be shown on a probability scale from 0 to 1.

  • A probability of 0 tells us that the event will never happen - it's impossible
  • A probability of 1 tells us that the event is certain to happen
  • A probability of tells us that the event has an even chance of happening
Unlikely events are closer to 0 and likely events are closer to 1.
