9. A worker needs to drive to work from his home daily. There is only one route available, on which there are two speeding cameras working independently. The speeding cameras at each of these locations operates 40% and 80% of the time respectively. Based on the worker's driving habit, he will speed 50% of the time; and whether he will speed at different time points are independent. What is the probability that the worker will not receive a speeding ticket for each day? Note: whether the camera is working at any time is also independent with whether a driver is speeding when s/he drives through that camera. (1 mark) о 0.72 0.48 0.36 Ӧ о 0.56
