Okay, I know what dependent events and independent events are, but where do we add and where do we multiply.
There is only one conclusion. There is no general hard-and-fast rule for probability. Sometimes you have to add, sometimes multiply, sometimes 1-(). It depends on the Question. And there is no explanation to why. So, basically, it's all screwed.
