Question 859796: Here is a question about probability i have had been having a hard time with
In a large shipment of boxes of cat food, 30% of the boxes are lightweight (below the marked label weight). Suppose that a random sample of boxes are drawn and weighed until 1 lightweight box is found. What is the probability that the sample size will be exactly 4?

I am taking this question to mean "what is the probability that the 1st 3 boxes weighed are not lightweight and the 4th is lightweight.
In that case: (7/10)^3 * 3/10 = 1029/10000
