# Math Help - Inclusion-Exclusion

1. ## Inclusion-Exclusion

A=10 and B=15

Find the maximum and minimum values AuB

Max=25, Min=15.

Am I correct?

2. As written the question makes no sence.
Do you mean that $A~\&~B$ are sets?
And $|A|=10~\&~|B|=15$ that is the number of elements in the sets.
Are you asks to find $\max\{|A\cup B|\}~\&~\min\{|A\cup B|\}$?

3. Sorry! Plato. I don't know how to input the symbol.
You are correct I am looking for ?

$\max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15$.
Why not learn to post in symbols? You can use LaTeX tags.
$$\max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15$$. gives $\max\{|A\cup B|\}=25~\&~\min\{|A\cup B|\}=15$.

5. Thank you very much! Plano. I will try to use symbol next time.
