@amistre64 good morning!

amistre64 · Answer

the given information can be organized in a chart:  

d, has the disease, d' has not
t, is a true result, f is false.

|dw:1391779611896:dw|

let a+b=1 account for the total population, and those with "d" amount to .0055

.0055+b = 1 will give us the value of b if needed.

good morning satelitte :)
