Use the Games of chance activity document to complete the following:
Write down how chance is built into the game. For example, does the game use a die, spinner, cards etc.?
Work out the sample space for each one.
Calculate the probability of each outcome.
Note: Don't choose Snakes and Ladders for one of your games as that is the example used in the document.

Bottle flipping was a trend in 2016 that involved throwing a plastic bottle, typically partially full of liquid, into the air so that it rotates, in an attempt to land it upright on its base. You are going to investigate the probability of achieving a successful ‘flip’.
Watch the video “Water Bottle Flip 2 | Dude Perfect” for inspiration.
Your flips do not have to be this inventive, BUT you do need to flip the bottle in the same manner each time.
Water Bottle Flip 2 | Dude Perfect
Duration: 4:57
Fill an empty bottle about half full of water.
Flip the bottle 20 times, trying to make it stand upright when it lands.
Count how many successful flips that you produce, out of the 20.
Calculate the probability of a successful flip and record your answer as a fraction, decimal and percentage, using the investigation Google Doc.
Alter the amount of water in the bottle and repeat the experiment.
Calculate the probability again.
Did it change?
Did you have more or less chance of a successful flip?
Alter the amount of water in the bottle, twice more, calculating the probability of a successful flip each time.
What do you notice about your results? Were you more or less successful when the water level was higher?

Play the Counter Plague game from the Motivate Maths website (PDF).
Imagine your school. Someone in your class comes in one morning with the Counter Plague. Who will get it? Will everyone in the class? Or will some people be OK? How about other classes? Will it spread to them as well?
