please i really need help The line plot below displays the fraction of incoming calls answered before the second ring by a group of employees. What fraction of employees answered less than of their incoming calls before the second ring?

Answer:
B
Step-by-step explanation:
If we count the number of points we find out that there are 36 employees
so the fraction must go like x/36
x is the numbers of dots that are less than a 1/2 which are 1/8, 1/4 and 3/8
so x=6
6/36
1/6
so option B
