Question
For the following exercises, determine whether set $A$ and set $B$ are equal, equivalent or neither.$A=\{$ John, Paul, George, Ringo $\} ; B=($ Bono, Larry, The Edge, Adam $\}$.
Step 1
Set $A$ has 4 elements (John, Paul, George, Ringo) and set $B$ also has 4 elements (Bono, Larry, The Edge, Adam). So, the number of elements in both sets is the same. Show more…

Set Operations with Two Sets
Prove that the following are equivalent for sets $A$, $B$, and $C$ : (a) $A \cap B=\varnothing$ (b) $B \subseteq \bar{A}$ (c) $A \Delta B=A \cup B$. where $\Delta$ is the symmetric difference operator (see Exercise Section

Prove that the following are equivalent for sets $A$, $B$, and $C$ : (a) $A \cup B=U$ (b) $\bar{A} \cap \bar{B}=\varnothing$ (c) $\bar{A} \subseteq B$. where $U$ is a universal set.
