Working out probability

Work out the probability of throwing an even number on a dice.

1. Count up the total number of possible results.
   When throwing a dice, for example, there are 6 possible numbers the dice can land on (1, 2 ,3 ,4, 5, 6).

2. Then count up the number of results you are interested in.
   In this example, you are only interested in throwing a 2, 4 or 6 (all the even numbers on a dice). So you are interested in 3 numbers.

3. The probability of getting an even number on a dice is 3 chances out of 6 chances which you write as ³/₆.
   ³/₆ is the same as ¹/₂ which can also be expressed as 'half', 0.5 or 50%.
