Likelihood Scale

If the probability of an event happening is between 0 and 50%, we say the event is "unlikely."

If the probability of an event happening is between 50 and 100%, we say the event is "likely."

The arrow shows that the probability of an event happening is about 10%. Is this event likely or unlikely?

• Unlikely (no es probable)

• Likely (probable)
