Learning Intention: CL4 - Find and justify straightforward probabilities based on equally likely outcomes in simple contexts (eg picking a heart out of a pack of cards)

Write a sensible sentences using each of the following word (Eg "There is a poor chance of rain today") is :

1. Certain

2. 50/50 chance

3. Impossible

4. Very likely

9. A number card or ‘not a picture card’

10. A card that is either a heart or a club

11. A card that is neither a heart or a club

12. p(4 or 5) =

13. p(4 or 5 but not a spade) =

14. p(even numbered card)=
