This video tutorial covers Math 7 Unit 8 Lesson 4, focusing on estimating probabilities through repeated experiments. It begins with an introduction to probability using decimals and explores probability through games and experiments. The lesson emphasizes understanding probability over repeated trials, defining sample space, and calculating outcomes. Students learn to plot probability results on a graph and analyze data from experiments. The tutorial also applies probability to real-world scenarios, concluding with a homework assignment.
