Answer:

$P\cup Q=\{1,\ 2,\ 3,\ 4,\ 5,\ 7,\ 8,\ 9, \ 10,\ 11\}$

Explanation:

The union of two sets P and Q, denoted as
$P\cup Q,$ is the set of all elements that are in the set P or in the set Q or in both sets P and Q.

Given:

P = {7, 8, 9, 10, 11}

Q = {1, 2, 3, 4, 5}

Then

$P\cup Q=\{1,\ 2,\ 3,\ 4,\ 5,\ 7,\ 8,\ 9, \ 10,\ 11\}$

When writing the union set, simply write all elements from both sets in on set.
