COM-B2-M08-P004 Two Identical Sets
#4
★★☆☆☆ Level 2 of 5
Let \(A_1=A_2=\{1,2\}\), \(A_3=\{2,3\}\). Find a system of distinct representatives.
Try either saving number \(2\) for the third set or not.
For example, choose \(1\in A_1\), \(2\in A_2\), and \(3\in A_3\). All representatives are distinct, so this is a system of distinct representatives.
A small problem on SDR language.
