What you'll learn

1. 1

   Imagine you have a bag with 3 red marbles and 1 blue marble. If you pick one without looking, you're more likely to get a red one because there are more reds!

2. 2

   If a bag has 3 red and 1 blue marble, which colour is MORE likely to be picked?

3. 3

   Drag the marbles to see the chance of picking a red one from a bag of 2 red and 2 blue marbles.

4. 4

   Let's find the probability of rolling a 4 on a dice.

5. 5

   What is the probability of rolling an EVEN number on a dice?
