1. If |P|=25, Q=30, IPQ=10, then find | PUQ| 2. In a discrete mathematics class every student is a major in computer science or mathematics or both. The number of students having computer science as a major (possibly along with mathematics) is 25; the number of students having mathematics as a major (possibly along with computer science) is 13; and the number of students majoring in both computer science and mathematics is 8. How many students are in the class? 3. Among 50 patients admitted to a hospital, 25 are diagnosed with pneumonia, 30 with bronchitis, and 10 with both pneumonia and bronchitis. Determine: (i) The number of patients diagnosed with pneumonia or bronchitis (or both). The number of patients not diagnosed with pneumonia or bronchitis **** **** Principle of Inclusion - Exclusion Formula for the number of elements in the union of two finite sets: A U BI=A+B|-|An B Formula for the number of elements in the union of three finite sets: AUBUC=A+B+C-AB-BOC-ANC+ AN BOC 1.
