Probability - what's the chance?

We have been looking at chance and probability.  Today we created this chart to help us see how fractions, percentages and words can all explain the chance of something happening.

Is it a fair chance?

We played a game using dice to see which horse would win the race.  We wondered why some numbers seemed to have better luck.  We decided to investigate......

When we tried again, we shared out the numbers with the greater chance.  The game was much more fair!
