Answer 2

Answer:

Concept:

A Venn diagram is a popular visual form that displays the logical link between sets. It was invented by John Venn in the 1880s. The diagrams are used in mathematics, logic, statistics, linguistics, and computer science to teach elementary set theory and to show simple set relationships. To depict sets, a Venn diagram uses basic closed arcs drawn on a plane. These curves are frequently circles or ellipses.

Given:

In a group of 20 adults, there are 8 males and 9 vegetarians. If the group has 5 male vegetarians, find the number of female non-vegetarians using a Venn diagram.

Find:

find the number of female non-vegetarians

Answer:

Number of adults $=20$

Number of males $=8$

vegetarians $=9$

male vegetarians $=5$

Find number of female vegetarians

Number of females = number of adults - number of males

                                 $=20-8\\=12$

Number of female vegetarians = vegetarians - male vegetarians

                                                     $=9-5\\=4$

Total Number of Female non-vegetarians $=12-8$

                                                                      $=4$

Therefore, female non-vegetarians $= 8$

Draw the circles that overlap in the center to make an intersecting Venn diagram. You'll be able to demonstrate which qualities are unique to

each circle, which overlap between two circles, and which are shared by all three groups. A classic venn diagram is two circles overlapping.
