Tо increаse schооl spirit аmong students аt Mount Apple Tree High (MATH), a principal began a program in which one student is randomly selected each week to receive a prize. Each of the school’s 250 students is equally likely to be selected each week, and the same student could be selected more than once. Each week’s selection is independent from every other week. Consider the probability that a particular student receives at least one prize in a 36-week school year. Define the random variable of interest. Explain why the distribution of this random variable is binomial. Calculate and interpret the expected value for the number of prizes a particular student will receive in a 36-week school year. Show your work (typed in the text box). Suppose that Lindsay, a student at the school, never receives a prize for an entire 36-week school year. Based on her experience, does Lindsay have a strong argument that the selection process was not truly random? Explain your answer.   Label each part clearly in the text box.
