It discusses without replacement probabilities using correct denominators, and explains that independent scoring probabilities must be multiplied rather than added. It also covers several applied methods including using circle pie chart areas and protractor angles, distance time graph gradients for greatest speed, and capture recapture estimates for fish and rabbits. The creator repeatedly checks quartiles, interquartile ranges, medians, and how to estimate areas under curves using rectangles or trapeziums for over or underestimates.
