Let A = {Dirk, Johan, Frans, Sarie}, B = {Frans, Sarie, Tina, Klaas, Henrika}, C = {Hans, Frans}. Find the number indicated. n(A ∪ (B ∪ C))

Thank you for posting your question here at I assume the question should be "Find the number indicated". below is the answers:

B U C means B union C which combines them:

{Frans, Sarie, Tina, Klaas, Henrika, Hans} note that there is no need to write Frans twice.

∩ means intersection which is only what the two sets have in common, in this case:

{Frans, Sarie}

the number is 2.

[tex]\boxed{ \bold{ \huge{ \boxed{ \bold{9}}}}}[/tex]

Step-by-step explanation:

Given,

A = { Dirk , Johan , Frans , Sarie }

B = { Frans , Sarie , Tina , Klass , Henrika }

To find : n ( A ) + n ( A )

Now, count the number of member of a set A

n ( A ) = 4

Also, Count the number of members of a set B

n ( B ) = 5

Finding n( A ) + n ( B )

= 4 + 5

= 9

Hope I helped!

Best regards! 😀
