Question 472893: Suppose a company that makes radios is interested in quality control of their factory. As a batch of product goes by on the assembly line, they randomly select two radios from each batch to inspect for defects. Now suppose for a particular batch tested there are 3 defective radios and 15 good radios. What is the probability that at least one of the radios selected for testing will be defective? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 15C2/18C2=105/153=.6863 probability that none selected for testing will be defective.
1-.6863=.3137 the probability that at least one of the radios selected for testing will be defective.
