In Stage 4 Probability 1, students have learned the terminology of probability such as outcomes, events, sample space and many more that students will see throughout Stage 4 and 5 of probability. Students have also learnt to assign a probability from 0 to 1 to an event to determine the likelihood of the event occurring or not occurring.
In Stage 4 Probability 2, students learnt the difference between mutually exclusive and non-mutually exclusives events. Learnt how to visually identify and represent events of probability in a two way table and Venn diagrams. And learnt new language of probability such as at least and inclusive or exclusive or.
In Stage 5.1 Probability students have conducted a variety of experiment that allowed them to recognize or understand the concept of randomness and chance. Be able to predict the probability or outcome of simple and compound events that students will later use again in Stage 5.2 .
