You can put this solution on YOUR website! The Probability(Pr) of the first ball drawn is black is 4/13
The Pr of the second ball drawn is black is 3/12 = 1/4
The Pr of the third ball drawn is black is 2/11
The Pr that all three balls drawn are black is (4/13)*(1/4)*(2/11) = 8/572 = 2/143 = 0.013986014
