If the weather is clear,the intruder is detected 90 percentof the time; If the weather is cloudy,the intruder is detected 82 percentof the time; and if the weather is rainy,the intruder is detected 54 percentof the time.

The three weather conditions occur according to the following percentages: Clear: 50 percent; Cloudy: 40 percent; and Rainy: 10 percent.
