Determine whether each statement is true or false. 1 ∈ {11, 5, 4, 3, 1}

Key Concepts

Set Notation

Set notation is a mathematical way to describe a collection of distinct objects, known as elements. In this context, the curly braces {} indicate a set, and the elements within are the specific values included in that set. Understanding set notation is crucial for determining membership, which is the focus of the question.

Element Membership

Element membership refers to whether a specific item is included in a set. The symbol '∈' denotes that an element belongs to a set, while '∉' indicates it does not. In the question, we are asked to evaluate if the number 1 is an element of the set {11, 5, 4, 3, 1}, which requires checking the presence of 1 among the listed elements.

True or False Statements

True or false statements are assertions that can be evaluated for their validity. In mathematics, determining the truth value of a statement often involves logical reasoning and analysis of definitions. The question requires assessing the truth value of the membership statement regarding the number 1 and its inclusion in the specified set.
