Summary

This unit builds on the earlier probability in Unit 9 to develop understanding of the use of diagrams, charts and tables in solving probability problems. The unit begins with a consideration of the impact of sample size on the relative frequency obtained. Graphs are used to support understanding. Tree diagrams are used to represent the outcome of dependent and independent events and to calculate the probabilities of these outcomes. Venn diagrams are also introduced to represent outcomes and to support the calculation of probabilities from real-life contexts and with an emphasis on developing reasoning skills. Two-way tables are then considered and the unit closes by exploring probability problems linked with other areas of mathematics such as algebra and data handing.

The Teaching Guide is outstanding in how it covers the exam board specifications.

PG Online have been a lifesaver for good quality schemes of work. The resources are really well thought out, really well paced and the homeworks and assessments test the core understanding of each lesson. I have also found the textbooks to be a great course companion.
