Look at this, this is very nontrivial but armed with this, we can now build up the truth table for all the cases of the two different variables, cancer and non-cancer and positive and negative tests outcome. So, let me write down cancer and test and let me go through different possibilities. We could have cancer or not, and the test may come up positive or negative. So, please give me the probability of the combination of those for the very first one, and as a hint, it’s kind of the same as before where we multiply two things, but you have to find the right things to multiple in this table over here. This is not an easy question.
