The odds of the first pick being a Republican is 5/13. If this happens the odds of the next pick being Republican is 4/12 If that happens, the odds of the last pick being Republican is 3/11.

They all have to happen so to get the final answer, multiply all these together. (5/13)*(1/3)*(3/11) = 15/429 or about 3.5%.
