Probability Experiments
Grade 4 probability formalizes experimental results as fractions: if heads appeared 8 times in 20 flips, the experimental probability is 8/20 = 2/5. This fraction representation bridges informal probability language (more likely, less likely) and the formal probability scale from 0 to 1. First Peoples games of chance demonstrate that probabilistic reasoning is embedded in traditional gaming culture across many nations.
