Sorry, I've never learned this before. Maybe @ganeshie8 knows?

anonymous · Answer

@Secret-Ninja Thank you for at least responding!

ganeshie8 · Answer

if $X$ and $Y$ are independent events then :
$$P(Y|X) = P(Y)$$

anonymous · Answer

@ganeshie8 there are no options of mine that have x's or y's in them, only a's and b's
Soooooo?

secret-ninja · Answer

They are variables so I am guessing that it doesn't matter what the letters are....

secret-ninja · Answer

The best answer I think it is is choice B because of what ganeshie8 said.

No problem, I wouldn't have dreamed of even guessing it if it weren't for ganeshie8. :)
