Three numbers are chosen at random without replacement from the set {0, 1, 2, 3, ... , 10}. Calculate the probabilities that for the three numbers drawn

what the probabilities that the sum is equal to 7

The only combinations that sum to 7 are these 4:

0+1+6 = 7
0+2+5 = 7
0+3+4 = 7
1+2+4 = 7

The number of combinations of 3 numbers are C(11,3) = 165
