Extracted text: QUESTION 9 The QMplus-gremlins are mischievous creatures that cause computer problems. After careful research you observe that the number of gremlins active each day is a random variable with Bin(3, 0.5) distribution. If no gremlins are active, the probability of QMplus failure is 0.15; if one gremlin is active the probability of QMplus failure is 0.3; if two or more gremlins are active the probability of QMplus failure is 0.5. You conclude that the total probability of QMplus failure on a given day is (to two decimal places). Assuming there is a failure, the probability no gremlins are active is (again to two decimal places).
