As of 1994, there were estimated to be 55 million people worldwide who engaged in alpine skiing. The estimated number of skiers, who practised alpine, cross-

This is the uniqueness statement of the Carathéodory extension theorem for finite measures. If this result does not seem very remarkable, consider the fact that it usually is very difficult or even impossible to fully describe every set in the "σ"-algebra, and so the problem of equating measures would be
