As the others have alluded, how the problem is stated is critically important.

For instance, if the question were "After rolling a 6, what is the probability of then flipping two heads?"

In that case, the (P=6) is 1, and the calculation would be" (P=6)*(P=H)*(P=H) = 1*(1/2)*(1/2) = 1/4 = 0.25 = 25%.

Um, if no one is using these quarters anymore.......

I teach 8th grade math and our book teaches what most of you have already said......1/24 chance ( 1/6*1/2*1/2)

So, I'm smarter than a 5th grader!?!

Actually you would be smarter than an 8th grader b/c most of my students never get a grasp of it!!
