Step 1 :The total number of ways to arrange 6 players is 6 factorial (6!). This can be represented as \(6!\).
Step 2 :There is only one way to arrange the players in alphabetical order.
Step 3 :Therefore, the probability of the players shooting in alphabetical order is \(\frac{1}{6!}\).
Step 4 :Final Answer: The probability that the six basketball players shoot free throws in alphabetical order is \(\boxed{\frac{1}{720}}\) or approximately \(\boxed{0.00139}\).
