we decided on a new logo for our brand of t-shirts.It was to be 3 stripes;(1) each stripe could be colored in 1 of 2 different colors,but we didn't want adjacent stripes to be the same color.how many different logos could we make.(2) how many more logos could we make if we used 3 colors instead of 2. (3) if we had used 4 stripes and 2 colors,how many more logos could we have made than using 3 stripes and 2 colors
