Problem 1: Prevalence of Students with Gastroenteritis (6 points, 2 points each)

Consider a class with 100 enrolled students. None of the students were ill at the beginning of the school year. On September 30, a total of 5 students reported having gastroenteritis. All 5 continued to be ill on October 1, but all 5 recovered within 3 days. On October 14, another 3 students developed gastroenteritis. All of these students continued to be ill on October 15, but all 3 recovered 5 days later. In this example, assume that a person cannot get gastroenteritis more than once.

  1. Calculate the point prevalence of gastroenteritis in the class on October 15th. Express the final answer as a percentage (multiplier of 100).
