Quizplus · Accepted Answer

The expected frequency for each type of music is calculated by dividing the total number of occurrences by the number of categories. Here, the total is 80 (Rock) + 72 (Pop) + 38 (Rap) = 190. There are 3 categories (Rock, Pop, Rap), so the expected frequency is 190 / 3 = 63.33 for each category.
