A certain office supply store stocks 2 sizes of self-stick notepads, each in 4 colors: blue, green, yellow, or pink. The store packs the notepads in packages that contain either 3 notepads of the same size and the same color or 3 notepads of the same size and of 3 different colors. “ If the order in which the colors are packed is not considered,” how many different packages of the types described above are possible?
(A) 6 (B) 8 (C) 16 (D) 24 (E) 32
“ If the order in which the colors are packed is not considered,”是说颜色不予考虑,还是颜色可以随意的意思呢? 求教! |
