Javier 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 30 3030 students. He simulated 100 100100 classes of 30 3030 students where each student selected had a 0.14 0.140, point, 14 probability of being left-handed. Javier counted how many left-handed students were in each simulated class. Here are his results: 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9# of left-handed students Use his results to estimate the probability that there are 7 77 or more left-handed students in a class of 30 3030 students. Give your answer as either a fraction or a decimal. P ( 7 or more left-handed ) ≈ P(7 or more left-handed)≈P, left parenthesis, 7, start text, space, o, r, space, m, o, r, e, space, l, e, f, t, negative, h, a, n, d, e, d, end text, right parenthesis, approximately equals
