If 12 identical balls are to be placed in 3 different boxes, then the probability that one of the boxes
\( \mathrm{P} \) contains exactly 3 balls is

W
(1) \( 220\left(\frac{1}{3}\right)^{12} \)
(2) \( 22\left(\frac{1}{3}\right)^{11} \)
(3) \( \frac{55}{3}\left(\frac{2}{3}\right)^{11} \)
(4) \( 55\left(\frac{2}{3}\right)^{10} \)
