Extracted text: A computer company redesigns its keyboards to reduce the width of its new line of laptops. Unfortunately each large key on the keyboard (such as the space bar or shift key) is defective with probability 0.03 and each small key is defective with probability 0.01. If key defects occur independently, what is the probability that exactly two large keys and one small key are defective on a laptop with 9 large keys and 55 small keys?
