hi,
here is the question,
jack receives instruction for 12 clients and uses color coding to identify each client , if either a single color or a pair of two colors is chosen to represent each client and if each client is uniquely represented by that choice of one or two colors , what is the minimum number of colors needed for the coding?(assume that the order of the colors in a pair does not matter)
thank you

Whoops! No answer choices. Believe the min number would be 7 colors.
