Question

A city has three newspapers A, B and C. Of the adult population, 1% read none of these newspapers. 36% read A, 40% read B, 52% read C, 8% read A and B, 11% read B and C, 13% read A and C and 3% read all the three newspapers. Required:
i. Illustrate the above information on a venn diagram
ii. What percent of the adult population read newspaper A only
iii. What percent of the adult population read newspaper B or Newspaper C
iv. What percent of the adult population read newspaper A or B but not C

Answer 1

Start the diagaram, with 3 circles all partially overlapping.  Label the circles A, B, C (labels go on the circumference arcs in such a way as not to interfere with placement, into the various separate portions that have arcs as their boundaries).

 

Put the percentage numbers into the correct regions, carefully.  Begin with 3 in the middle portion that is part of each of the circles. Then work outward from this 'center', making sure to make the numbers consistent, i.e. for that part representing just A and C, you put 10 (because 3% are already accounted for in the ABC 'center').

 

Consult your textbook for similar examples.  Do it yourself--you'll pretty soon get the hang of it.
