The Cartesian product $C \times N$ pairs each element of set $C$ with each element of set $N$, resulting in all possible ordered pairs: $\text { (red, circle) }$, $\text { (red, square) }$, $\text { (green, circle) }$, $\text { (green, square) }$.

Let C={ red, green }N={ circle, square }\begin{array} { l } C = \{ \text { red, green } \} \\N = \{ \text { circle, square } \}\end{array}C={ red, green }N={ circle, square }​

Let $\begin{array} { l } C = \{ \text { red, green } \} \\N = \{ \text { circle, square } \}\end{array}$
