Extracted text: 4. A manufacturer of tablet ipods is concerned about the possible recall of their best selling model. If there was a recall, there is a 0.30 probability that a defect is in the videocard, 0.20 in the audiocard, 0.18 in the memory card, and 0.45 in some other areas. What is the probability that the defect is the videocard or the memory card if the probability of defects in both parts simultaneously is 0.20?
