Parts exiting an assembly line are inspected and categorized as good or bad (defective). In a batch of 100 parts, 8 were found to be defective.
What is the probability that a part drawn at random is defective?
Number of parts exiting an assembly line which are bad(defective) = 8
Total number of parts passing the assembly line = 100
Probability of part being defective =Number of defective partsTotal number of parts
Probability of a part being defective =8100=0.08
