Vedclass · Answer

(B, C) Given the set $A = \{1, 2, \{3, 4\}, 5\}$.$1$. The elements of $A$ are $1$,$2$,$\{3, 4\}$,and $5$.$2$. Since $\{3, 4\}$ is an element of $A$,the statement $\{3, 4\} \in A$ is true.$3$. Since $\{3, 4\}$ is an element of $A$,the set containing this element,which is $\{\{3, 4\}\}$,is a subset of $A$. Therefore,$\{\{3, 4\}\} \subset A$ is also true.$4$. The elements $3$ and $4$ are not individual elements of $A$; they are part of the set $\{3, 4\}$. Thus,$\{3, 4\} \subset A$ is false,and $\{1, 3, 5\} \subset A$ is false.

Let $A = \{1, 2, \{3, 4\}, 5\}$. Which of the following statements are true?
