Example Questions
Example Question #42 : Data Analysis
Aracely posted a survey question using one of her social network accounts. She grouped the results into three categories. The response results are represented by the Venn diagram shown above.
Group represents the respondents that answered "yes" to the survey question. Group represents the respondents that answered "no" to the survey question. And, the overlapping part of the diagram represents the respondents that answered "maybe" to the survey question.
What fraction represents the amount of respondents that answered "yes" to the survey question?
The Venn diagram shows that exactly percent of the survey respondents answered "yes" to the survey question.
Thus, to find the fraction equivalent we need to rewrite
From here we simplify the fraction.
Example Question #1652 : Isee Lower Level (Grades 5 6) Quantitative Reasoning
The Venn diagram shown above has three categories that represent information about the Wildcats varsity baseball team.
Category represents the number of players on the team that are left-handed.
Category represents the numebr of players on the team that are pitchers.
And, the overlapping portion of the Venn diagram represents the number of players that are left-handed pitchers.
Given that and that there are players in the overlapping region of the diagram.
How many players are right-handed pitchers?
Since the question provides the information that there are left-handed pitchers and total pitchers, one can infer that the number of right-handed pitchers is equal to the difference between the total number of pitchers and the number of left-handed pitchers.
Thus, the solution is:
Example Question #91 : Data Analysis And Probability
The Venn diagram shown above has three categories that represent information about the Wildcats varsity baseball team.
Category represents the number of players on the team that are left-handed.
Category represents the numebr of players on the team that are pitchers.
And, the overlapping portion of the Venn diagram represents the number of players that are left-handed pitchers.
Given that and that there are players in the overlapping region of the diagram.
What fraction of the players are only left-handed?
Since, there are left-handed players total and left-handed pitchers there must be players that are left-handed but do not pitch, because .
To find what fraction this represents we need to do:
Example Question #101 : Data Analysis And Probability
In the above Venn diagram category represents the number of Kevin's friends that play the flute, while category represents the number of Kevin's friends that play the bass.
If of Kevin's friends only play the flute and of his friends only play the bass, then what fraction of Kevin's friends play both instruments?
To find the fraction of Kevin's friends that play both the bass and the flute, consider that the fraction represents all of Kevin's friends in this senario.
Thus, the solution can be found by adding those that only play flute with those that only play bass and subtracting that final answer from the fraqction that represents all of Kevin's friends:
Example Question #3 : How To Use A Venn Diagram
In the above Venn diagram category represents the number of Kevin's friends that play the flute, while category represents the number of Kevin's friends that play the bass.
If of Kevin's friends only play the flute and of his friends only play the bass, then what percentage of Kevin's friends only only play the bass?
of Kevin's friends only play the bass.
Thus, to find the fractional equivalent we need to multiply the fraction by 100.
The solution becomes:
Example Question #51 : Data Analysis
The Venn diagram above represents the results from a recent survey given to middle school students. Category represents the amount of students that only like pizza. Category represents the amount of students that only chicken nuggets.
What percentage of students only like pizza?
Since Category represents the amount of students that only like pizza--and shows an amount of percent in the Venn diagram, no calculations need to be performed.
