a. How many total students are at the school?

b. What is the probability that a randomly chosen student will by lunch between 10 and 20 times in a month?

A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.

The total number of students = 140 + 120 + 80 + 40 + 30 + 60 = 470

What is the probability?

The probability that a randomly chosen student will by lunch between 10 and 20 times in a month = number of students between 10 and 20 times / total number of students

(80 + 40) / 470 = 0.26
