Answer:
a. 20 students have brown hair
b. 1/7
c. 5%
d. 36.66%
Step-by-step explanation:
a. You add all the numbers beneath "Brown" together.
b. You find the total number of blonde hair students (14). Then you find the total number of students with both blonde hair and hazel eyes (2). Now you divide the number of students with both(2) by the total number of blonde students (14) Then you get the fraction 2/14 then you simplify this to get your answer. 1/7.
c. You add all the number together to find the total number of students. Then you find the number of students with both green eyes and red hair (3) You divide this number by the total number of students (60). You then get 3/60= .05 which is 5%.
d. First you add the number of green eyed students (13) to the number of red haired students (9) which then you get 22. You divide 22 by the total number of students (60) this gives you a decimal of .36666 on forever. This would be 36.6 % with bar notation over the 6 after the decimal point to represent that the decimal never ends.
Hopefully this is correct and helps you : )
