What is the green ball?
Before colour TV balls used in statistics were coloured black and white. Statistical questions were posed asking, say, the probability of selecting a white ball from a mixture of black and white balls hidden in a bag (sometimes white and black balls). A practical set up that, over a large number of tries, would show that the maths being examined was (statistically) good. Since colour TV there has been a preponderance of the use of coloured balls in the experiments and, often, one of the colours used is green. Also, using colour allows more than two different things to be the subject of statistical experiment. Of course colour TVs had nothing to do with this but the rest is true - honest. Beano GB
