So if this area has A, this area is B, and the intersection where they overlap is C, the combined area is going to be A plus B minus where they overlap, minus C. So that's the same thing over here. We're counting all the jacks, and that includes the jack of hearts. We're counting all the hearts, and that includes the jack of hearts. So we counted the jack of hearts twice, so we have to subtract one out of that. So it's gonna be four plus 13 minus one, or this is going to be 1650 seconds, and both of these things are divisible by four, so this is going to be the same thing as, divide 16 by four, you get four. 52 divided by four is 13. So there's a 413th chance that you get a jack or a hearts.
