Everyday Chance Events

Everything we do it has a chance of happening. From guessing what will the weather be tomorrow, to being involved in a car accident, learning something new at school and getting some free time to play a game on the iPad. We can always describe that with chance.

Describing Chance Situations Using Vocabulary

We can use certain vocabulary to describe the chance that a situation is going to happen.

If something “will never” happen, then we can say that it is impossible.

If something “always happens“, then we can say that it is certain.

If something is probably not going to happen, then we can say it is unlikely.

If something is probably going to happen, then we can say it is likely.
