[quote=Anonymous]The question is ambiguous. Is it asking probability of shuffling on just one day of the week? Or the much smaller probability of shuffling every day for seven days? If the former, I think it's 28%. If the latter, I think it's something like 0.0135% (i.e., 28%^7). I haven't done probabilities in several years, so it this is a high schooler looking for homework help, you may well miss this one.[/quote]
