Why is freeway paving sometimes concrete and sometimes asphalt?
In southern California, and probably elsewhere, freeways are paved with both concrete and asphalt, seemingly at random. I know that the roadway surface on a concrete bridge is concrete, but in other places, why is concrete used sometimes and asphalt used other times? And why do they alternate?
9 AnswersEngineering1 decade agoWhat is the probability that 2 M&Ms have the same color when 3 are drawn?
I've got a large bag of M&Ms, large enough that the supply can be considered infinite. Furthermore, I'll assume that all six colors I observe are in the same quantity. If I take 3 M&Ms from the bag, what is the probability that two, and only two, M&Ms are the same color? What is your reasoning?
