Explanation of Solution
Given:
The given diagram is shown in Figure 1
Figure 1
Calculation:
The probability that the 2 ball and the 11 ball will be the first and the second is the row is equal to the number of ways in the remaining 6 balls can be arranged divided by the total number of ways 8 ball pools can be arranged.
Then,
