A study of underwater sounds in a specific region of the Pacific Ocean focused on scarce sounds, 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 scream) = .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.
