There are 25 computers in a store. Among them, 20 are brand new and 5 are refurbished. Six computers are purchased for a student lab. From the first look, they are indistinguishable, so the six computers are selected at random. Compute the probability that among the chosen computers (i) two are refurbished. (ii) at least two are not refurbished.
