In the example dealing with what happens to supermarket fliers, we found that the probability that a flier carrying a “do not litter” message would end up in the trash, if what people do with fliers is independent of the message that is on them, was .033. I also said that 4.5% of those messages actually ended up in the trash. What does this tell you about the effectiveness of messages?
