Intersection of two setsThe intersection of two sets are all the elements that appear in both sets. For example, if you have the two sets of numbers: {3,4,5}, and {5,6,7}, the intersection of these sets is:{5} because only 5 appears in both sets. The symbol for intersection is an upside-down capital U, so if we call our first set "A" and our second set "B" then
Now, here's a problem for you: Set A: 5, 8, 3, 4, 5, 5, 9, 9 Set B: 3, 8, 8, 9, 3, 4, 0, 0 What is A ∩ B = {___, ____, ____, ____, _____, ____} Hint: Circle the elements of B that you find also in A. |
