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.
