Probability: the rules of probability are quite simple but it takes a little effort to understand.

The key thing that trips people up is when they need to add probabilities, and when they need to multiply them.

The best way to learn about how to answer probability is not to try to get the answer from someone with regard a specific question, but read about it in a maths textbook or some other introduction to maths. This will tell you how to calculate and do probability and then it is just a case of applying it to each question that you attempt to answer.
