I am throwing one red, one blue and one yellow ball on a grid type table and log each trial. I log the distance of red and blue balls to the yellow one. After 100 trial, i have a historical data and now i calculate probability of yellow ball each time i put them on the table. I am getting percentile using blue-yellow distance and percentile using red-yellow distance. Of course both of them gives different results. I am not searching for an accurate one but is there a way to come up with one result instead of two?
Let's say red-yellow tells me 75th percentile is going to be 105cm from the bottom edge of the table and the blue-yellow tells me 75th percentile is going to be 83cm from the bottom edge of the table.
