Suppose that I am buying 12 sets of iphones that are either
black, white, green, or...
Suppose that I am buying 12 sets of iphones that are either
black, white, green, or red. Suppose that each iphone of the same
colour are indistinguishable from one another. How many
combinations are there such that I have at least 2 black sets and
at most 1 red set?
Repeat question 1 with the additional requirement that I would
still have at least 1 set of blue headphone if I break 3 iphones
sets randomly over the next month.
Ignoring the restrictions from the previous questions, suppose
that I bought 3 sets of iphones of each colour . I place them in a
circle for display. Suppose that the positions of the headphone
sets in that circle matters, meaning, rotation of the same ordering
counts as a different arrangement. How many ways can I do that if
no 2 white iphones sets can be placed next to each other?
