So how DO you solve this math problem? I must admit, I've forgotten all the math probabilities I've ever learned (I don't think I had them until my probability and statistics class in grad school), and would be the first to shout out ".28!!"

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'm OP, I'm a mom, my kid is at Deal and this a math problem the kids are doing in their little impromptu math club--it was presented to them as being high school level.

Do your own homework, kid.

It isn't a brain teaser.

Now can we solve this poor kids math problem.

I really like this one. I impressed my kids with my pop/lock moves.

For a parent, who math learning ended at Trigonometry, how did you get your answer. I did know all the dances and songs.

Too funy!

This is correct.
I sure learned a whole lot about dancing just now.

Opps. kid's. Sorry.

If it were a 5th (?) grade problem introducing probabilities, then I'd think it was looking for just one-day probability. But if high school, I'd think seven-day consecutive probability.

That's what the imperfect grammar was attempting to make clear. I think it's trying to say: "Every day, I'm [doing a, b, c, or d]." Poorly written, especially for a math problem.

Totally agree. While "every day, I'm shuffling" sounds grammatically incorrect, it's actually correct and precise in the context of this assignment and makes it very clear that the answer is looking for "I'm shuffling" on all of the days (each and every day). In an English essay, you'd probably say "every day, I shuffle" to express a habit.

No wonder that the rest of the world thinks German should be the language of choice for science and math (as French for diplomacy). The English language does not do well on math problems, which, come to think of it, may be one reason the US trails so many other countries when it comes to math.
