two part question:

Q1: what is The probability that a unit ends up in rework (in decimal form)

Q2: what is the probability that a defective unit is shipped (in decimal form)

please answer both questions, thank you.

Consider an assembly line with 20 stations. Each station has a 0.5% probability of making a defect. At the end of the line, an inspection step singles out the defective units. The inspection step catches 80%6 of all defects. From inspection, units that are deemed to be non-defective are moved to the shipping department. If a defect is found at inspection, it is sent to the rework department. Rework fixes about 95% of the defective units. Units are directly shipped from the rework department with no further inspection taking place. What is the probability that a untit ends up in rework (in decimal form)
