Acoustical engineers conducted a study of rare underwater sounds in a specific region of the Pacific Ocean, such as humpback whale screams, dolphin whistles, and sounds from passing ships (Acoustical Physics, Vol. 56, 2010). During the month of September (non-rainy season), research revealed the following probabilities of rare sounds: P(whale stream) = .03, P(ship sound) = .14, and P(rain) = 0 If a sound is picked up by the acoustical equipment placed in this region of the Pacific Ocean, is it more likely to be a whale scream or a sound from a passing ship? Explain.
