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.
Why do you think that the question is ambiguous, PP? While the tense of the problem statement is poorly chosen, I don't see how to read it as asking for anything other than the probability of shuffling every day for 7 days, which is (p_s)^7 = .4^7= .0016384.

I suppose the Dougie/shuffling/popping and locking references were supposed to connect with the kids, but I would have found it a rather pathetic attempt.

This is a high school level question. That's depressing.

Oops. I'm overthinking it. Now I agree with PP that the answer is 0.16% (i.e., 0.4^7).

Instead of correcting the spelling, solve the math problem, genius.

No, a high schooler's mother is posting the math homework. Maybe it's the OP of the thread on too high expectations....
