Unique set size
Okay kiddo, let's talk about unique set size!
Imagine you have a bunch of toys, like blocks or Legos. You can use them to build different things, like a house or a car. The toys you have make up a set.
Now, if you have ten different toys, that means your set size is ten. But if some of the toys are the same, like if you have two red blocks, then your set size is smaller because those blocks aren't unique.
Unique means one of a kind, like if you have a toy that no one else has. So, when we talk about unique set size, we mean how many different things there are in the set.
For example, let's say you have a pile of fruit: two apples, two bananas, and two oranges. Even though you have six pieces of fruit, your unique set size is only three because you only have three different kinds of fruit.
So, unique set size tells us how many different things are in a set, without counting duplicates or things that are exactly the same. Pretty neat, right?
