Problem
Chayton read a report that said the probability that a randomly selected American is left-handed is
14
%
14%14, percent. He was curious how many left-handed students to expect in a class of
20
2020 students.
He simulated
25
2525 classes of
20
2020 students where each student selected had a
0.14
0.140, point, 14 probability of being left-handed.
Chayton counted how many left-handed students were in each simulated class. Here are his results:
A dot plot for number of left-handed students has a scale from 0 to 5. The number of dots for each is as follows. 0, 0. 1, 4. 2, 5. 3, 11. 4, 4. 5, 1.

Use his results to estimate the probability that there are
2
22 or fewer left-handed students in a class of
20
2020 students.
