Lucky Sausage

A group of parents running a fundraising sausage sizzle are struggling to keep up with demand, so have got the BBQ turned up to the hottest setting. As a result, one third of the sausages are burnt, a quarter are sold before they are cooked properly, but the rest are fine. 

1) Use coloured cubes to model this situation, 

2) Find the theoretical percentage probability, that the next customer is lucky enough to get a properly cooked sausage. 

3) Run a short experiment (i.e pulling cubes out of a bag) and record the results. Do they match with the theoretical percentage? Why or why not?

Show all working on an A3 sheet and show your teacher when your group is finished.
