표기:
 $A,B$ 의 '''결합확률'''을 $P(A\cap B),\,P[AB]$ 등으로 표기함.

교집합intersection, and(conjunction)과 관련

계산식:
> $P[AB]=P[B|A]P[A]=P[A|B]P[B]$
특히 사건 $A, B$ 가 독립이면([[독립성,independence#s-2]])
> $P[AB]=P[A]P[B]$

= 조건부확률과의 비교 =
[[조건부확률,conditional_probability]]은,
 $P(B|A)=\frac{P(A\cap B)}{P(A)}\;\;(P(A)\ne 0)$ 이고 마찬가지로,
 $P(A|B)=\frac{P(A\cap B)}{P(B)}\;\;(P(B)\ne 0)$
그래서 '''결합확률'''은,
 $P(A\cap B)=P(B|A)P(A)=P(A|B)P(B)$
