High school students using their cell phones to text in class is a major problem in disrupting the learning experience. Suppose whether or not a student texts in a high school class is a binomial random variable with a success probability p = 0.60. Out of a class of 20 students, find the probability that 11 or more students, but 15 or less text in class (i.e., either 11, 12, 13, 14, or 15 students)
