4) Brightlite company makes light bulbs. The state of the company's machines can be: Available for use and being used OR available for use but not needed OR broken down. a) The table shows the probabilities of the state of the machines in July 1994. What is the missing probability? State of machines: July 1994 Probability Available for use, being used Available for use, not needed 0.09 Broken down 0.03 b) During another month the probability of a machine being available for use was 0.92. What was the probability of a machine being broken down? c) Brightlite calculated the probabilities of a bulb failing within 1000 hours and within 2000 hours. Copy and complete the table below to show the probabilities of a bulb still working at 1000 hours and at 2000 hours. Time Failed Still working At 1000 hours 0.07 At 2000 hours 0.57
