Set A is composed of a single member "8"Set B has three members of the "7", "8" and "9"and see how "8" is in both sets. We can say that the whole of A figure of the series B, or that the set a is A subset of set B, due to this fact. Consider the possibility of a Venn Diagram. Draw a circle representing set B. Fill in the circle with "7", "8" and "9". Then, draw a smaller circle around the "8" to represent this as the set A. Visually you can see that is inside of B completely. There are parts that are outside of the B. If you threw a dart and it landed in To, then we are also within B as well. This is the same as saying: "we've chosen the '8' out of a hat, so they came to A or a set B". So to summarize, it is a subset of B. Using mathematical notation, we could write this as . The "C" looking symbol (it's not really a (C) means "subset".
