Probability

The relative likelihood of a particular outcome among all possible outcomes.

probability

the likelihood of a particular uncertain event occurring, measured on a scale from 0.0 (such an event is impossible) to 1.0 (such an event is certain to occur). People generally estimate probabilities on the basis of the relative frequency with which an event has occurred in the past, under given circumstances, and generalize from this past experience. In some circumstances it is easy to estimate the proportion of occasions on which an event occurs; for example, the probability of getting ‘heads’ when flipping a balanced coin is 0.5 because with such a coin in the long run we would get 50% ‘heads’ and 50% ‘tails’. In estimating probabilities in business situations, though, there may be no or only a few previous experiences that can be used to gauge the relative frequency of an event occurring.

The distance was little more than six miles, but the road was strange, and I had to keep stopping to inquire my way; hallooing to carters and clodhoppers, and frequently invading the cottages, for there were few abroad that winter's morning; sometimes knocking up the lazy people from their beds, for where so little work was to be done, perhaps so little food and fire to be had, they cared not to curtail their slumbers.
