充分必要条件 Necessity and sufficiency

(重定向自Sufficient)

充分及必要条件sufficient and necessary condition)简称「充要条件」。

在逻辑学中:

  • 当命题「若A则B」为真时,A称为B的充分条件,B称为A的必要条件

因此:

  • 当命题「若A则B」与「若B则A」皆为真时,A是B的充分必要条件,同时,B也是A的充分必要条件
  • 当命题「若A则B」为真,而「若B则A」为假时,我们称A是B的充分不必要条件,B是A的必要不充分条件,反之亦然。

Necessity and sufficiency 充分必要条件

(重定向自Sufficient)
The sun being above the horizon is a necessary condition for direct sunlight; but it is not a sufficient condition as something else may be casting a shadow, e.g. in the case of an eclipse.
That a train runs on schedule can be a sufficient condition for arriving on time (if one boards the train and it departs on time, then one will arrive on time); but it is not always a necessary condition, since there are other ways to travel (if the train does not run to time, one could still arrive on time through other means of transport).
Consider two logical statements S and N, such that S is sufficient for N (if S is true, then N must also be true). Figuratively, if we are within S then we are within N. It follows that S cannot be true unless N is true – i.e., that N is a necessary condition for S.
Dass ein Korb da ist, ist eine notwendige Bedingung, um Basketball spielen zu können – ohne ihn geht es nicht.

In logic, necessity and sufficiency are implicational relationships between statements. The assertion that one statement is a necessary and sufficient condition of another means that the former statement is true if and only if the latter is true. That is, the two statements must be either simultaneously true or simultaneously false. In ordinary English, 'necessary' and 'sufficient' indicate relations between conditions or states of affairs, not statements. Being a male sibling is a necessary and sufficient condition for being a brother. Fred's being a male sibling is necessary and sufficient for the truth of the statement that Fred is a brother.
