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.

Let’s assume that one drop is equal to 50 µl. a total of 2366 drops will fill how many tablespoons?

lina2011 [118]

First, we have to set the volume in 1 tablespoon. It actually depends on the country you're living. In USA, 1 tablespoon is approximately 14.8 ml. In microliters, that is equal to 14,800 μL. Thus,

Volume of the liquid = 50 μL/drop * 2366 drops = 118,300 μL
Therefore, that is equivalent to
Number of tablespoons = 118,300 μL/14,800 μL = 7.99924 or approximately 8 tablespoons
