Step-by-step explanation:
Given Data:
Length of rectangle = L = ------->(Equation 1)
Area of rectangle = A = square inches ------->(Equation 2)
To find out:
Width of rectangle = W = ?
Formula:
Area = A = L×W
Solution:
For complete division check the attached image.
inches
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.
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.
