What is the probability that Kevin has diabetes and the test predicts this?  
This means that it asks for when Kevin has diabetes 0.75 and the test predicts it 0.85
You just need to multiply these: 0.6375

We now know that the test predicted that Kevin does not have the disease. Using this information, calculate the probability that Kevin does not have diabetes after the test was taken. what about this?

It is a much more interesting question: 
What is the probability that the test predicts diabetes?

anonymous · Answer

i really need help with this???

anonymous · Answer

For that question you just need a bit of logic. 
0.6375 we get for the first question. 
An event has to have all the probabilities add up to 1. 
1-0.6375=0.3625
What is this probability?
