Main Question or Discussion Point

I was wondering, if you are told that for two events A and B, We Have P(A)=0.4 and $P(A\mid B) = 0.4$\\
Can you assume as P(A) = P(A\mid B) That these events are independent?
regards
Brendan

Sorry guys,

That was Latex fonts

It should be
IF P(A) = 0.4 and P(A|B) = 0.4 can we assume that events A and B are independent?

regards

Yes. To show this use

A, B are independent if and only if [tex]P(A\cap B)=P(A)P(B)[/tex],

[tex]P(A|B)P(B)=P(A\cap B)[/tex].
