18 Rare underwater sounds. 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.
