# 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**.

It is certain that if you will get wet if you go out in the rain.

It is impossible that a elephant will fly into the school.

It is likely that it will be colder in July that it will be in January.

It is unlikely that we will fly to the moon.
