Beta, it's all about whether events can hold hands or not. Independent ones live separately—like my tabla practice not affecting the rain outside—so for "or," you simply add. But if they're exclusive, they refuse to share space, so you must subtract their overlap, just like I had to subtract marks for mixing them up on my test. That failure is why I now see it clearly, sitting here on this balcony, counting only the deodars, not the mist between them.
