Kaylee read a report that said the probability that a randomly selected American is left-handed is 14\%14%14, percent. She was curious how many left-handed students to expect in a class of 252525 students. She simulated 404040 classes of 252525 students where each student selected had a 0.140.140, point, 14 probability of being left-handed. Kaylee counted how many left-handed students were in each simulated class. Here are her results: Use her results to estimate the probability that there are fewer than 333 left-handed students in a class of 252525 students. Give your answer as either a fraction or a decimal. P(\text{fewer than } 3 \text{ left-handed})\approxP(fewer than 3 left-handed)≈P, left parenthesis, start text, f, e, w, e, r, space, t, h, a, n, space, end text, 3, start text, space, l, e, f, t, negative, h, a, n, d, e, d, end text, right parenthesis, approximately equals
