The company representative concludes that the consumer is very unlikely to encounter problems with a software upgrade. As support, the representative cites the fact that the company has distributed many copies of the upgrade but has received only a few calls from users who had problems.
The representative draws a conclusion about the likelihood of a problem based on evidence about how many people have called the company about that problem. This fails to consider the possibility that more users may have had problems with the upgrade, but did not call the company about their problems.
