因为联合是a和b中所有元素的总和,a和b有相同数量的元素,2x-1001=20072x=3008x=1504.所以答案是1504.故选C.Let x be the number of elements in A and B.Since the union is the sum of all elements in A and B,and A and B have the same number of elements then,2x-1001=20072x=3008x=1504...
Noun1.Venn diagram- a diagram that uses circles to represent mathematical or logical sets pictorially inside a rectangle (the universal set); elements that are common to more than one set are represented by intersections of the circles
Each circle contains the number 3, which means that each group has 3 elements. This data can be plotted as another Venn diagram with the percentage.The Venn diagram shows two non-overlapping circles named names1 and names2. We have a total of 3+3 = 6 items in the Venn diagram. names1...
Reading a Venn diagram is simple. All you have to do is look at the circles in the diagram. If the circles overlap with each other, then that means there are some similar elements on both sets. If the circles do not overlap, then that means there are no similar elements....

Step 3: Edit Venn Diagram and Text Keep in mind that all elements in a Venn diagram can be edited, modified, or treated independently. This means you can remove one symbol and replace it with another, edit text only, etc. so here is how you edit your diagram: ...
The meaning of VENN DIAGRAM is a graph that employs closed curves and especially circles to represent logical relations between and operations on sets and the terms of propositions by the inclusion, exclusion, or intersection of the curves.
