Three companies #1, #2, and #3 provide 50%, 30%, and 20% of steel to a construction site. From past records, the percentages of bad quality steel provided by these companies are 3%, 4%, and 5%, respectively. A steel sample is selected randomly and is found to be of bad quality.
1) What is the probability that this steel sample is coming from company #1?
2) What is the probability that the bad quality sample was produced by either company #1 or #3?
Homework Answers
From the given information,
1. As percentage for company 1 is 50%
Hence,
Probability that the steel sample is coming from company 1 is 0.5
2. probability that the bad quality sample was produced by either company #1 or #3 is,
P=0.03+0.05
P=0.08
Thank you.
