Eight numbers are selected at random from the unit interval.
(a) Find the probability that the first four numbers are less than 0.25 and the last four are greater than 0.25.
(b) Find the probability that four numbers are less than 0.25 and four are greater than 0.25.
(c) Find the probability that the first three numbers are less than 0.25, the next two are between 0.25 and 0.75, and the last three are greater than 0.75.
(d) Find the probability that three numbers are less than 0.25, two are between 0.25 and
0.75, and three are greater than 0.75.
(e) Find the probability that the first four numbers are less than 0.25 and the last four are greater than 0.75.
(f) Find the probability that four numbers are less than 0.25 and four are greater than 0.75
