P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4
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.
I Think The answer is 35 units I hope it helps Message Me if I’m wrong and I’ll change My answer and fix it for you
Solving the inequality 
we get
