I said that it wont be useful as the first line of the question said that the 2 types (A-B) were mutually exclusive so I said that they had nothing in common

I said that the test was usefull since the probability of having type A was 0.7 so it's more likely the person has typeA

well even tho they were mutually exclusive, don't you think there's a probability of having no diseases of disease A

BAC123Hi

Can’t remember the question too clearly but I can remember doing 3x(3/4) because it asked after 3 rolls and I believe for 3 probabilities and each probability was 1/4.
