Probability = 

The successful numbers are these 4: {9,10,11,12}
The possible numbers are these 12: {1,2,3,4,5,6,7,8,9,10,11,12}

The number of successful choices are "4 things choose 2", or C(4,2) =  = 6

The number of possible choices are "12 things choose 2", or C(12,2) =  = 66

Probability =  =  =
