A workshop makes tables. The cutting and sanding operations areindependent. Based on historical data, under normal conditions, 1%of cut wood for the tables, and 2% of sanded wood for the tablesare defective. Assume that one table is randomly selected from alot of cut and sanded tables. a. What is the probability that atleast one of the operations (cutting and sanding) will bedefective? b. What is the probability that in a production lot of10 tables, none of the tables is defective? c. What is the expectednumber of defective tables in a production lot of 15 tables? Whatis the standard deviation?
