The process standard deviation is , and the process control is set at plus or minus standard deviations . Units with weights less than or greater than ounces will be classified as defects. What is the probability of a defect (to 4 decimals)?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
