Let Dequals​{14​,17​,19​}, Eequals​{14​,16​,17​,18​} and Fequals​{13​,15​,16​,17​,19​}.
List the elements in the set D union E.

Respuesta :

Answer:

{14,16,17,18,19}

Step-by-step explanation:

Given the elements in sets,

[tex]D=[/tex]{[tex]14,17,19[/tex]}

[tex]E=[/tex]{[tex]14,16,17,18[/tex]}

[tex]F=[/tex]{[tex]13,15,16,17,19[/tex]}

[tex]D[/tex]∪[tex]E[/tex] is asked to be found.

Now it is clear that [tex]F[/tex] is unnecessary for this question.

[tex]D[/tex]∪[tex]E[/tex]=[tex]D+E-(D[/tex]∩[tex]E)[/tex]

[tex]D[/tex]∪[tex]E[/tex]={14,17,19}+{14,16,17,18}-{14,17}

[tex]D[/tex]∪[tex]E[/tex]={14,16,17,18,19}
