    Study Notes

    Sufficient Conditions

    • A sufficient condition for B means A guarantees B's occurrence.
    • If A is true, then B must also be true; A's occurrence necessitates B's.
    • All instances of A are included within the set of B.

    Necessary Conditions

    • A necessary condition for B indicates that B guarantees the occurrence of A.
    • If B is true, then A must also be true; B’s occurrence requires A's existence.
    • All instances of B must include A to occur.

    Necessary and Sufficient Conditions

    • A condition is both necessary and sufficient for B when A guarantees B and B guarantees A.
    • If A occurs, then B occurs, and vice versa; A's existence is tied to B, and B’s existence is linked to A.
    • All instances of A are also instances of B, and all instances of B are instances of A.
