WebbIt is referred to as associative property of union of sets. It looks something like this; (AUB)UC = AU (BUC) In simple words, changing the order in which operations are performed does not change the answer. the operations inside the brackets are solved first. For Example: A= {1,2} B= {3,4} and C= [5,6] then (AUB)UC is; AUB= {1,2,3,4} Now, Webb7 apr. 2024 · a Intersection b Formula When two sets (M and N) intersect, then the cardinal number of their union can be calculated in two ways: 1.
