An aerospace company builds a type of cruise missiles. Suppose, on average, the first failure of this type of missiles occurs on the last firing per every 20 successive independent firings. In a successive independent firings of such missiles, if the first failure occurs after at least 10 firings, what's the probability that it occurs after 15 firings? (Round your answer to the nearest ten thousandth.)
