Answer:
Option B is correct.
y =32x represents a proportional relationship.
Step-by-step explanation:
If two quantities are said to have a proportional relationship if they vary in such a way that one of the quantities is a constant multiple of the other i.e,
y = |k| y where |k| is constant proportionality.
By definition :
y =32x where k =32 is constant , represents a proportional relationship.
I just write not possible
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.
