**Educational Content: Probability and Inspection Quality**### Context**Washer City: We Sell Washers... And That's All!**Washers, characterized as discs with holes in the middle, are crucial components in the assembly of certain products. The internal diameter of these washers must comply with precise specifications. Based on historical data from thorough manual inspections, it has been noted that:- 75% of washers meet the required specifications.- 15% are larger than specified.- 10% are smaller than specified.To minimize reliance on manual inspections, a new electronic inspection machine has been introduced. This machine:- Correctly identifies washers meeting specifications 95% of the time.- Correctly identifies washers not meeting specifications 80% of the time.### Problems**Question 15**Given that a washer fails to meet specifications, what is the probability that it is too big?\[ \text{Let } p \text{ denote this probability.} \]**Question 16**If the electronic inspection machine reports that a washer does not meet specifications, what is the probability that the washer actually does meet the specs?These questions involve calculating conditional probabilities based on the performance data of the inspection system and the distribution of washer sizes. Through solving, you will gain insights into the reliability and accuracy of the inspection machine used by Washer City.

Proportion of washers that meet specifications = 75% (0.75)Proportion of washers that are too big =…
