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?
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
