There are approximately 131,000 cases of colorectal cancer in the US each year ( data as of 1998). The US pop is approx 270 million. What's is the probability that a randomly selected person in the US will develop this type of cancer during a year? What method of assigning probabilities are you doing to make this determination?

131,000/270,000,000 = ?
