Each set has 15 Comract elements. The pair-wise intersections have 5 elements each. The 37 three-way intersections have 2 elements each. There is only one element in the intersection of all four sets. What is the size of the There are (;1) pairwise intersections, each of which has 5 union? elements. There are (g) three-way intersections, each of 37 which has 2 elements. There is only one intersection of z all four sets. eck Sh ow answer 4.15_('21)54-(§)2—1=60—6-5+4'2—1=37 CHALLENGE . : : - | ACTIVITY 3.12.1: The general inclusion-exclusion principle.
