Parts and what they mean
- E ∩ F′ (E ∩ F′) — In E but not in F. With E \cap F it makes up all of E: P(E) = P(E \cap F) + P(E \cap F') (used in Example 13).
- E ∩ F (E ∩ F) — Both E and F happen.
- E′ ∩ F (E′ ∩ F) — In F but not in E.
- E′ ∩ F′ (E′ ∩ F′) — Neither E nor F — the part of S outside both circles.
- A partition of S (S का एक विभाजन) — \{E \cap F', E \cap F, E' \cap F, E' \cap F'\} are pairwise disjoint and their union is S (Section 13.5.1).
