Probability starters Power Point and a better pimped up version, thanks to Dianne Meyer (2010 PP version)

- Probability language & describing chance
- The concept of randomness
- Quantifying chance
- Number of outcomes (Probability theory) - listing outcomes, tables, two way tables, trees
- Long run relative frequency
- Probability distributions
- Experiment vs Theory (And the effect of sample size)

### For Teachers

* Be familiar with the Achievement Standard AS1.13 #91038 (link to NZQA)

* Check the latest information on the NZQA clarifications page

* Look over the NZQA Annotated Examples on AS1.13 Probability.

* AS 1.13 section on Nayland Web site updated: May 2015

1.13 Probability is a 3 credit internally assessed topic AS 91038

Probability investigates the chance of things happening (events) and what the expected result may be.
Experimental probabilities, simulations and tree diagrams will be used.

*Compare and describe the variation between theoretical and experimental distributions in situations that involve elements of chance.

*Investigate situations that involve elements of chance:
- comparing discrete theoretical distributions and experimental distributions, appreciating the role of sample size
- calculating probabilities in discrete situations.
