7. EXAMPLE : A welding robot in an automobile plant looks for a small magnetic dot to perform a spot weld. The robot has an 85% success rate for finding the dot. If it can not find the dot on the first try, it is programmed to search again. b) The assembly line moves so fast, the robot only has 3 seconds before the dot is out of range. What is the probability that the robot will find the dot before it is out of range ?
