Let U = {q, r, s, t, u, v, w, x, y, z} A = {q, s, u, w, y} B = {q, s, y, z} C = {v, w, x, y, z}. List the elements in the set: A
gtnhenbr [62]

Answer:

A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}

Step-by-step explanation:

Given: \text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}, \text{A}=\left \{\text{q, s, u, w, y} \right \}, \text{B}=\left \{\text{q, s, y, z} \right \},

\text{C}=\left \{\text{v, w, x, y, z} \right \}.

To find: The elements in the set A \cup C.

Solution:

We have,

\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}

\text{A}=\left \{\text{q, s, u, w, y} \right \}

\text{B}=\left \{\text{q, s, y, z} \right \}

\text{C}=\left \{\text{v, w, x, y, z} \right \}

Now, A \cup C will contain all the elements in the set A and all the elements in set C.

So, A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}.

Hence, A \cup C=\left \{  \text{q, s, u, v, w, x, y, z} \right \}.
