Identify the event “greater than 9” if the sample space is {0, 1, 1, 2, 4, 5, 7, 9, 10, 11, 11, 12}.
A: {10, 11, 11, 12}
B:{9, 10,11,11,12}
C:{10,11,12}
D: { 0, 1, 1, 2, 4, 5, 7}
The event "greater than 9" refers to the set of outcomes in the sample space that are greater than 9.
From the given sample space {0, 1, 1, 2, 4, 5, 7, 9, 10, 11, 11, 12}, the outcomes that are greater than 9 are {10, 11, 11, 12}.
Therefore, the correct answer is A: {10, 11, 11, 12}.
