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)

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

1 Answer

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.
