Answer:
1/3,575,880
Explanation:
To solve for this problem we need to find for each possibility.
We will have:
1/45 for the first route.
1/44 for the second route.
1/43 for the third route.
1/42 for the fourth route.
This is considering that the candidate will not be in the same capital twice.
So we simply multiply all of the possibilities.
1/45 x 1/44 x 1/43 x 1/42 = 1/3,575,880
So there will be a 1/3,575,880 possibility that the candidate will select the route of the four specific capitals.
