Suppose that F is a continuous dj. on the real line; and let at and 02 be numbers such that F(at) - 0.3 and F(a,) - 0.8. If 25 observations are selected at random from the distribution for which the dJ. is F, what is the probability that six of the observed values will be less than ah ten of the observed values will be between at and a2 , and nine of the observed values will be greater than 02?
