if P(A) = 0.2 P(B) = 0.4 P(AorC) = 0.7
P(AIC) =??
answer係P(AIC) = P(A)xP(C) / P(C) = P(A) = 0.2
但係唔明,如果你畫個venn diagram出黎.
P(A given C) = P (A) = 0.2
咁係唔係話A係C入面!?
因為P(AIC) = P(A)
P(AIC)係唔係話probability of A given in C?
更新1:
咁P(A) in C = P(A) 仲唔係P(A)成個係C?
更新2:
yes they are independent sorry i forgot to tell that
