An urn contains five blue balls and six yellow balls. If six balls are selected randomly without being replaced, what is the probability that of the balls selected, two of them will be blue and four of them will be yellow? The probability that of the balls selected, two of them will be blue and four of them will be yellow is (Round to four decimal places as needed.)
