Suppose a sample space is a deck of \(52\) playing cards. Let set \(A=\{ \text{Aces} \}\) and \(B=\{ \text{Kings} \}\) and use a Venn diagram to show that \(A\) and \(B\) are mutually exclusive.
Use a Venn diagram to show the intersection of the set \(A=\{\text{Aces}\}\) and \(B=\{\text{Spades}\}\) from the sample space of a deck of playing cards.
Let \(A\) and \(B\) be two intersecting sets, neither of which is a subset of the other. Use a Venn diagram to illustrate the set \[\{x\mid x\in A\text{ and }x\notin B\}\]
