  • The quality of being frequent; often occurrence; the happening often in the ordinary course of things.
  • The ratio of the number of times that an event occurs in the ordinary course of events to the number of occasions on which it might occur; with a few recent writers on physics, the number of regularly recurring events of any given kind in a given time.
