Question

A frequency bar graph is shown for the shoe size of a class of 9th graders at Brookwood High School. What is the probability that a student wears size 12 shoes (round to the nearest hundredth)?

Answer 1

I saw the image. I'll just write the values but I also attached the image needed for this problem.

shoe size     frequency
7                            7
8                           16 
9                           19
10                         27
11                         33 
12                         35
total                   137

Probability that a student wears size 12 shoes is 0.255 or 25.5%.

P = 35/137 = 0.255
