Use the symbol for βis a subset ofβ or βis not a subset ofβ to fill in the gap. The Venn diagram shows the set of seven and four, what, π.

The Venn diagram shows two different shapes. There is the triangle which is labelled π. And inside the triangle we can see an oval labelled π. The question gives us a statement that isnβt complete. Weβre told that the Venn diagram shows that a set containing the elements seven and four is either a subset of π or is not a subset of π. We have to choose the correct symbol to complete the statement with.

This symbol is the one we use if we want to show that something is a subset of something else. We use the same symbol but with a line through it to show that something is not a subset of something else. The statement mentions the letter π. So, the part of the Venn diagram we need to be looking at is the oval. If we look at the oval we can see that the π is a set, and it contains the elements five and seven. It doesnβt contain a number four which appears in the question. And so a set containing the elements seven and four is not a subset of π.

The symbol that we need to use in our answer is this one. π only contains the elements five and seven. And so a set containing the elements seven and four is not a subset of π.
