Roll two red dice and a green dice. Add the two numbers on the red dice and take away the number on the green. What are all the different possibilities that could come up?
Bipin is in a game show and he has picked a red ball out of 10
balls. He wins a large sum of money, but can you use the
information to decided what he should do next?
Mrs. Smith had emptied packets of chocolate-covered mice, plastic
frogs and gummi-worms into a cauldron for treats. What treat is
Trixie most likely to pick out?
Anna and Becky were playing a game. They put one purple cube and
two yellow cubes into a bag.
First Anna picked a cube out of the bag without looking, then
Becky picked one out.
If the two cubes the girls picked out were the same colour, Anna
won the game. If they picked out two differently coloured cubes,
then Becky was the the winner.
Is this a fair game?
Explain your answer.
Thank you to Doug Williams from the
Task Centre Project for this problem. If you'd like to take
this idea a bit further, look at In a Box.
