Use the image to answer the question.
A histogram is titled "Number of Siblings" with number of siblings on the horizontal axis and frequency on the y-axis. Four columns are plotted. The number of siblings ranges from 1 to 4 in increments of 1. The frequency ranges from 0 to 13 in increments of 1. The graph shows the following data: the frequency of 1 sibling is 12, the frequency of 2 siblings is 5, the frequency of 3 siblings is 3, and the frequency of 4 siblings is 1.
Students were asked the number of siblings they have, and the data are represented in the histogram. What percentage of students have 2 or more siblings? Round to the nearest whole number.

The total number of students surveyed can be calculated by adding up the frequencies of each category: 12 + 5 + 3 + 1 = 21.
The percentage of students who have 2 or more siblings can be calculated by adding up the frequencies of the categories with 2 or more siblings (2, 3, and 4) and dividing by the total number of students, then multiplying by 100 to get a percentage:
(5 + 3 + 1) / 21 * 100 = 47.6%
Rounded to the nearest whole number, approximately 48% of students have 2 or more siblings.

Apologies for the oversight. Let's calculate the percentage of students who have 2 or more siblings correctly:
The total number of students surveyed is 12 (for 1 sibling) + 5 (for 2 siblings) + 3 (for 3 siblings) + 1 (for 4 siblings) = 21 students.
The number of students with 2 or more siblings is 5 (students with 2 siblings) + 3 (students with 3 siblings) + 1 (students with 4 siblings) = 9 students.
To calculate the percentage of students who have 2 or more siblings, we divide the number of students with 2 or more siblings by the total number of surveyed students and then multiply by 100:
(9 / 21) * 100 = 42.86%
Rounded to the nearest whole number, approximately 43% of students have 2 or more siblings.
