On a line segment AB of length l, two points C and D are placed at random and independently. What is the probability that C is closer to D than to A? PS I understand that the marginal pdfs are f = 1/l, but how can I find the joint pdf?

1. A point P is chosen with a uniform probability distribution around a circle of radius r Let Z be a random variable that measures the absolute value of the distance of P from the y-axis (a) What is the mean and the variance of Z? (Hint, define an appropriately normalized uniform probability density function for the angle 0 describing the polar angle of the position P on the circle.) (b) Does your answer for the mean make sense? (c)...

*** SOLVE WITHOUT DERIVATIVE, USE GRAPHING CALCULATOR FUNCTION AND SHOW STEPS 4. Uniform Distributions. A random number generator randomly selects a number from -2 to 1. It is equally likely to select any number from this interval [-2,1]. We can view this random variable as a continuous random variable. (a) What is the constant height required to ensure that the area between the x axis and the curve is exactly one in this case (note since this is a uniform...

4. Uniform Stick-Breaking A point X is chosen uniformly from the interval (0, 10) and then a point Y is chosen uniformly from the interval (0, X). This can be imagined as snapping a stick of length 10 and then snapping one of the broken bits. Such processes are called stick-breaking processes. a) Find E(X) and Var(X). See Section 15.3 of the textbook for the variance of the uniform. b) Find E(Y) and Var(Y) by conditioning on X. Uniform (a,...
