Eyeglassomatic manufactures eyeglasses for different retailers. They test to see how many defective lenses they made in a time period. The folllowing table gives the type of defect and the number of lenses with that defect. Assume categories are mutually exclusive. Defect Type Scratch Right shaped - small Flaked Wrong axis Chamfer wrong Crazing, cracks Wrong shape Wrong PD Spots and bubbles Wrong height Right shape - big Lost in lab Spots/bubbles - intern Frequency 5638 4542 1773 1372 1417 1296 1580 1561 1200 Give your answer as a fraction. 1166 1512 990 987 a) Find the probability that a randomly selected defect from the table will be in the categor "Crazing, cracks" or the category "Right shape - big". Give your answer rounded to three decimal places. b) Find the probability that a randomly selected defect is not in the category "Crazing, cracks". Given your answer as a fraction. Give your answer rounded to three decimal places.
