3.n a certain residential suburb of 240 households, 120 use the TV, 130 the newspaper, and 140 the Internet to get their news. If 80 families use both the TV and the newspaper, 90 both the Internet and the newspaper, 70 the TV and the Internet, and 50 use all three, what proportion of households use exactly one source to get their news?

Choose a point at random from the unit square [0, 1] × [0, 1]. We also choose the second random point, independent of the first, uniformly on the line segment between (0, 0) and (1, 0). The random variable A is the area of a triangle with its corners at (0, 0) and the two selected points. Find the probability density function (pdf) of A.

(Display a Circle and Its Attributes) Write a program that displays a circle of random size and calculates and displays the area, radius, diameter and circumference. Use the following equations: diameter = 2 × radius, area = π × radius2, circumference = 2 × π × radius. Use the constant Math.PI for pi (π). All drawing should be done on a subclass of JPanel, and the results of the calculations should be displayed in a read-only JTextArea.
