In a class of 42 pupils, 25 enjoy basketball, and 10 are fans of netball. Notably, 4 pupils appreciate both sports. To determine how many pupils dislike both basketball and netball, we can use the principle of inclusion-exclusion. By calculating the number of pupils who like at least one of the sports, we can find out how many are not interested in either. Engaging with this problem enhances understanding of set theory and logical reasoning, making it a valuable exercise for students.
