How many does not read any newspaper? [stat problem]

  1. Mar 12, 2014 #1
    1. The problem statement, all variables and given/known data

    We have a town we three papers.

    Paper 1 is read by 64 % of pop.
    Paper 2 is read by 46 % of pop.
    Paper 3 is read by 54% of pop.

    3% read both Paper 1 and Paper 2.

    8% read both Paper 1 and Paper 3.

    12 % read Paper 2 and Paper 3.

    5% read all three papers.


    2. Relevant equations



    3. The attempt at a solution

    I have two questions.

    1) How many (in %) does not read either of three papers?
    2) How many (in %) reads at least one paper?

    1) Is that 100 % - 5 % = 95 ??

    Have you set up a "Venn Diagram"?

    I don't know what you mean by "either of three papers". I have never seen "either" applied to three things before. Do you mean "reads exactly one paper" or "reads at least one paper"?
