Question

18. According to Scientific American, 15% of people are left-handed. In a classroom with 100 students there are 10 left-handed seats available. What is the probability that it will be short of left-handed seats? Identify an appropriate probability model and express this probability. a) X = number of left-handed seats, X ? B(10, 0.15); P(X > 10) b) X = number of left-handed students, X ? B(100, 0.15); P(X ? 10) c) X = number of left-handed students, X ? B(100, 0.15); P(X > 10) d) X = number of left-handed students, X ? B(100, 0.85); P(X > 10) e) X = number of left-handed seats, X ? B(100, 0.15); P(X > 10)
