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.
Answer:
1) they equation they solved was correct as they were able to do the correct operation to yield their answer.
2)this problem should be approached by subbing in the correct X values and y values into their rightful position, by doing this U will yrild the correct answer
