Of every hundred pounds that's invested, round about forty pounds goes straight to the government in betting duty, round about thirty pounds goes to the football pools in expenses, commissions and profits, leaving round about thirty pounds to be returned in prizes, and so you can see that your rate of return on football pools is extremely small, but on the other hand a very large number of people do enter the football pools, and when they win they can win considerable sums of money and it can make absolute rational economic sense to go in for football pools because you are giving yourself a chance, no matter how small, of winning a sum of money that you wouldn't expect to come across in any other way of your life.
