Assume that you have decided to sample your production run and you assume that you sample is representative of the population of parts. You sample 192 parts at random. You find that 108 parts meet specifications, while 23 parts should be re-manufactured to meet specifications. The remaining parts cannot be re-manufactured and must be discarded. You select the two parts at random for inspection. What is the probability that both parts should be re-manufactured? Report your answer to the third decimal point, that is, 0.452 instead of 0.45 or 0.5

Report your answer to the third decimal point, that is, 0.452 instead of 0.45 or 0.5
Total number of parts sampled = 192
Number of parts that meet specifications = 108
Number of parts that should be re-manufactured = 23
We need to find the probability that both parts should be re-manufactured.
