P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4
$P(2\ good)=4C2\times0.75^{2}\times0.25^{2}=0.211$
$P(3\ good)=4C3\times0.75^{3}\times0.25=0.422$
$P(4\ good)=0.75^{4}=0.316$
The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
