Suppose that the distribution of people's ages in the United States is essentially constant, or uniform, from age 0 to age 60, and from there it decreases linearly until age 100.This distribution p(x)is shown below, where x is age in years, and p measures probability density.Such a probability distribution is called trapezoidal. In terms of the length of the base, b, of the trapezoidal distribution (notice that the base of the trapezoid lies along the p-axis), find the fraction of the population that is between 0 and 60 years old.
A)20b
B)60b
C)40b
D)80b
