The range of a set of numbers is the difference between the largest and smallest values in the set. To find the range of the set {4, 9, 6, 3, 2, 8, 10, 11}, we need to find the largest and smallest values in the set and then subtract the smallest value from the largest value.
The smallest value in the set is 2 and the largest value is 11. So, the range is 11 - 2 = 9.
So, the range of the set {4, 9, 6, 3, 2, 8, 10, 11} is 9.
