Sufficient condition

From CreationWiki, the encyclopedia of creation science
Jump to navigationJump to search

An event A is said to be a sufficient condition for event B whenever the occurrence of A is all that is required for the occurrence of B.[1]

A sufficient condition is a condition that, if true, proves that another fact is true. For example:

  • "Breathing is a sufficient condition of living." If you are breathing, then you are definitely alive."
  • "Having polio is a sufficient condition of being infected with poliovirus." If you have polio, then you have definitely been infected with polio virus.

The other type of condition is a necessary condition.
