tonya and lauren are desinging a soccer uniform they want to use two colors on the shirt their choices are green orange yellow purple blue and silver how many ways can they choose two colors?
math organized list -
6 colours, of which we pick 2 .....
are we "choosing" ?
then we have C(6,2) = 15
If the arrangement of colours matters, then we would have
6x5 or 30 ways
