Can I deduce marital status after observing person > **Possible Duplicate:** > percentage calculation After reinterpret this question percentage calculation I have idea that, by observing person not only name I could not, but also marital status I can't deduce, so answer would be $2/8*100=25$%, sorry for repeating question, (tomorrow I have midterm so wanted to know actual answer on this question)

Your variables are: Name, Age, Gender, Height, Weight, Eye color, Hair color and Marital status, and you are asked which of these you cannot deduce by observation.

Can you deduce a person's weight by observation alone? Can you deduce a person's age?

Perhaps it depends on your powers of observation. Good luck with your midterm.
