If eight numbers are randomly selected without replacement from set {1, 2, 3, 4, 5, 6, 7, 8}, what is the probability that the numbers are selected in ascending order?
Choose the correct option.
A) 1/25600 B) 1/36240 C) 1/48360 D) 1/24120 E) 1/40320
The total number of ways to arrange 8 numbers is 8! = 40320.   There is only one way to arrange the numbers in ascending order.   P(ascending order) = 1/40320   The answer is 1/40320.
