Example 5: An automobile assembly plant produces sheet metal door panels. Each panel moves on an assembly line. As the panel passes a robot, a mechanical arm will perform spot welding at different locations. Each location has a magnetic dot painted where the weld is to be made. The robot is programmed to locate the dot and perform the weld. However, experience shows that the robot is only 85% successful at locating the dot. If it cannot locate the dot, it is programmed to try again . The robot will keep trying until it finds the dot or the panel moves out of range. a) What is the probability that the robot's first success will be on attempts n = 1, 2, or 3? b) The assembly line moves so fast that the robot only has a maximum of three chances before the door panel is out of reach. What is the probability that the robot is successful in completing the weld before the panel is out of reach? Homework: Day 2: pg 550, 8.48, 8.49; pg 551 – 8.51, 8.53, 8.54, 8.55

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
