Give an example in which two events exhibit conditional independence with an event B but not with B complement.

Are there any examples of events A and B such that P(A∩B|C)=P(A|C)P(B|C) but not with C'? Especially with dice or coins? or is there any specific example?

There is an urn with two balls, black and white. You also have a fair coin. You flip the coin, and then...

  • If the result is heads, you draw two balls from the urn with replacement.

  • If the result is tails, you draw two balls form the urn without replacement.

Let $C$ be the event the coin is heads, let $A$ be the event the first ball you draw is white, and let $B$ be the event that the second balls is black. Clearly, $A$ and $B$ are conditionally independent given $C$, but $A$ and $B$ are conditionally dependent given $\overline C$.
