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

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

| Why did you save your homework for tonight? |

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. |

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

| Doesn't UMD have a policy on academic dishonesty? You can discuss your homework, but you are just coming on here for answers. |

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

Your precious spell check won't help you with your atrocious grammar, though! |

| 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. |

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. |
