A bond analyst was given a list of 12 corporate bonds. From that list she selected 4 whose ratings she felt were in danger of being downgraded in the next year, In actuality, a total of 5 of the 12 bonds on the list had their ratings downgraded in the next year. Suppose that the analyst had simply chosen 4 bonds randomly from this list. What is the probability that at least 2 of the chosen bonds would be among those whose ratings were to be downgraded in the next year? (Round to four decimal places as needed)
