As written the question makes no sence.

Do you mean that $\displaystyle A~\&~B$ are sets?

And $\displaystyle |A|=10~\&~|B|=15$ that is the number of elements in the sets.

Are you asks to find $\displaystyle \max\{|A\cup B|\}~\&~\min\{|A\cup B|\}$? - Apr 15th 2010, 02:05 PMquestionboy
Sorry! Plato. I don't know how to input the symbol.

You are correct I am looking for http://www.mathhelpforum.com/math-he...97e2f3c6-1.gif? - Apr 15th 2010, 02:22 PMPlato
$\displaystyle \max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15$.

Why not learn to post in symbols? You can use LaTeX tags.

[tex]\max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15[/tex]. gives $\displaystyle \max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15$. - Apr 15th 2010, 02:44 PMquestionboy
Thank you very much! Plano. I will try to use symbol next time.
