Question

As part of a class project, a university student surveyed the students in the cafeteria lunch line to look for a relationship between eye color and hair color among students. This table contains the results of the survey. What percentage of the sample population had blue eyes and black hair?

2.97%

10.59%

10.35%

28.05%

Answer 1

You forgot your table, but I will give an example as for how to answer this question: You need to multiply the percentage of people with black hair by the percentage of people with blue eyes. best change the percentage into numbers.

An example:

people with blue eyes: 25%, which is 1/4
People with black hair: 30%, that is 3/10

so we multiply:

`(1*3)/(4*10) = (3)/(40) =0.075=7.5%`%

This is just an example, you need to insert your numbers!
