Probability
Probability from the Gr 9 lesson plans: listing outcomes, expected and relative frequency, comparing experiment with theory, compound events with two-way tables and tree diagrams.
Lessons
71
Listing Possible Outcomes
Outcomes, events and sample spaces for single events: listing possibilities and calculating probabilities on a die.
2
Expected Frequency and Relative Frequency
Trials, frequencies, expected frequencies and relative frequencies, including the 50-toss coin experiment.
3
Comparing Relative Frequency with Probability
Comparing experimental relative frequencies with theoretical probabilities and explaining differences.
4
Compound Events and Two-Way Tables
Compound events and how two-way tables list every combined outcome, with the coin-and-die example.
5
Probability from Two-Way Tables
Reading class and dice two-way tables to find AND, OR and NOT probabilities without double-counting.
6
Tree Diagrams for Compound Events
Independent events and tree diagrams for two coins, balls with replacement, three coins, and coin-and-die.
7
Relative Frequency versus Probability
Button-and-coin tree probabilities in sequence compared with relative frequencies from 25 recorded turns.
