Federalism in the United States (video) | Khan Academy
Federalism is a pact between a national government and its states, with layers like a cake. In the U.S., it's more like a marble cake, with mixed and overlapping powers. Some powers are exclusive to the federal or state governments, while others are shared. This structure shapes how the U.S. operates.

Two-way frequency tables and Venn diagrams - Khan Academy
Sometimes data belongs to more than one category. For example, candies might have chocolate, coconut, both, or neither. We can use Venn diagrams and two-way tables. Venn diagrams show sets and their overlaps. Two-way tables organize data in rows and columns. Both methods help show relationships between categories.
