题目
设 B subset A ，则下列等式正确的是( )A. P(AB) = 1 - P(A)B. P(overline(B) - overline(A)) = P(overline(B)) - P(overline(A))C. P(B/A) = P(B)D. P(A/overline(B)) = P(A)
设 $ B \subset A $，则下列等式正确的是( )
A. $P(AB) = 1 - P(A)$
B. $P(\overline{B} - \overline{A}) = P(\overline{B}) - P(\overline{A})$
C. $P(B/A) = P(B)$
D. $P(A/\overline{B}) = P(A)$
题目解答
答案
B. $P(\overline{B} - \overline{A}) = P(\overline{B}) - P(\overline{A})$
