"That is an assumption, which you are making. If that were the case, question doesn't have to state "Rain on Saturday" case explicitly.". I repeat its an inference, maths leaves no room for assumptions. Even the question setter didn't consider the trivial condition in the answer choices.
I didn't assume anything. I just used exact information mentioned in the question. Question didn't say that P(Saturday no rain) has any impact on Sunday. Therefore, P(Sunday Rain) when there is no rain on Saturday will remain as .6. Period.
As it is not a GMAT question, I don't care what the choices are. I have seen several questions that are incorrect (some of them are posted in this form, which Instructors agree that they are incorrect). If the correct answer given is anything other than .84, I would throw this question into trash.
