The Attempt at a Solution

The superimposed diagram shows that the probability of a noncommunicable disease in a underdeveloped country is 0.37. But it's not correct…

I tried 0.56*0.78 = 0.44 as the probability of a noncommunicable disease in a underdeveloped country since the probability of a death from a noncommunicable disease is 0.56 and the probability of death in a underdeveloped country is 0.78. The answer is also wrong..

What am I doing wrong. How do you solve this?

it looks like the images are venn diagrams. From the middle diagram you get the .22 in the D set which in the third diagram is 0.02+0.01+0.19

So how would you find the orange area ie the 0.37 area given the 0.78 and the 0.09 and the 0.32?

In the third diagram, you are only interested in the areas that relate to the given condition. What are the numbers in those?

Conditional probability questions should look something like:
P(N|U)=P(N and U)/P(U).
You have both of those probabilities.
