Instead of counting study groups that include at least one of Alicia, Bob, and Sue, we will count study groups that don’t include any of Alicia, Bob, or Sue. To form such a study group, we just need to choose at least 2 of the remaining 17 ... WebMar 27, 2024 · Principle : Inclusion-Exclusion principle says that for any number of finite sets , Union of the sets is given by = Sum of sizes of all single sets – Sum of all 2-set intersections + Sum of all the 3-set intersections – Sum of all 4-set intersections .. + Sum of all the i-set intersections. In general it can be said that, Properties :
