C. P(A and B)=P(A) x P(B l A)
D. P(A l B)=P(A) if A and B are independent

anonymous · Answer

that was wrong, sorry
 P(A l B)=P(A) if A and B are independent is true by definition

anonymous · Answer

both B and C are also always true, again pretty much by the definition
only A is wrong

anonymous · Answer

Ohh dang this math website lied to me lol it told me that, like you said, A was correct. No wonder I've failed it like 4 times lol

anonymous · Answer

Can you explain the definition please?

zarkon · Answer

$$P(A|B)=\frac{P(A\cap B)}{P(B)}$$

anonymous · Answer

Words? lol

Ohh nevermind I see. Thanks to the both of you
