What is probability?

Probability in maths is the area that deals with the chance of something happening.

What words do we use to describe probability?

There are 7 terms we use to describe probability:

Impossible: There is no way this can happen;  example - a man growing to be 200 ft tall.

Very unlikely: This will probably not happen but could; example - winning the lottery.

Unlikely: This has more chance of not happening than it does of happening; example - rolling a six on a dice.

Evens: This has two things that could happen that are equally likely; example - tossing a coin and getting a head.

Likely: This has more chance of happening than it does of not happening; example - picking a consonant from the alphabet at random.

Very likely: This will probably happen but might not; example - using your phone today before you go to bed.

Certain: This has to happen; example - rolling a normal dice and getting a number less than 7.

When do I use words to describe probability?

Most probability is described using a number, so you should only use words if the question specifically asks you to.
