Ten Fibonacci numbers are split into three sets: A = {1, 2}, B = {3, 5, 8}, and C = {13, 21, 34, 55, 89}. One number is chosen at random from each set. What is the probability that their sum is odd?

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).
