The probability of visiting seven cities in alphabetical order out of seven randomly chosen routes is 1 out of 7 factorial (7!), because there is only one way to arrange the cities in alphabetical order out of the 7! possible arrangements. 7! equals 5040, so the probability is 1/5040, which equals approximately 0.00019841, rounded to five decimal places as 0.00020.
