Answer:
0.008
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Total outcomes:
He will visit 5 different cities. So the total number of ways this can happen is an arrangment of 5 elements, that is:
[tex]T = A_{5} = 5! = 120[/tex]
Desired outcome:
In alphabetical order, so only one possible outcome, which means that [tex]D = 1[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{120} = 0.008[/tex
