Probabilities are written as FRACTIONS.

On the **top **of the fraction, we put the number of ways there are of your event happening.

On the **bottom **of the fraction, we put the total number of possible outcomes.

Reduce the fraction if you can.

**Example**

There are 3 red balls and 5 blue balls in a bag.

What is the probability of choosing a red ball?

**Answer**

On the **top **of the fraction, we put the number of ways there are of your event happening. This will be the number of red balls (i.e. 3)

On the **bottom **of the fraction, we put the total number of possible outcomes. This will be the total number of balls (3 + 5 = 8)

The probability is **3/8**
