industry based on the perfection of color, weight, and length which are expressed by the variables C, W, and L, respectively. If a feature is perfect the machine takes input as ‘1’, ‘0’ otherwise. Based on the conditions, the machine decides whether to reject (R) a product or not. Assume R = 1, if the weight is not perfect as well as if any
Activity 5:
An automated QA machine selects the product in an industry based on the perfection of color,
weight, and length which are expressed by the variables C, W, and L, respectively. If a feature is
perfect the machine takes input as ‘1’, ‘0’ otherwise. Based on the conditions, the machine decides
whether to reject (R) a product or not. Assume R = 1, if the weight is not perfect as well as if any
of the color or length is not perfect. Otherwise, R = 0.
