In this episode, Don brings Charlie a notebook that was found on the body. It contains horse racing data and equations. Charlie determines that the equations were designed to pick the SECOND place winner, not first place. Parts of these equations use the "logit" function, a specific probability function that uses logarithms and odds ratios. Because the logit function can get pretty complicated, this activity lays its foundations, namely the relationship between probability, odds, and odds ratios.
