All these problems are basically mathematical proofs. What I am looking for is systematic and rigorous application of the formulas of probability. Be very clear and explain what you are doing..
Here, by "first principles", the author means that you start with the definition of conditional probablity and the definition of logical connectives. The proof is trivial. So you have to show systematically what elementary principles you are using at each step.
The key to this problem is the rigorous and frequent application of the formula for conditional probability. Once again, clarity on how you are moving from one step to another is important.
