- Randomly choose a number X from the density f X ( x ) = x 8 for 0 ≤ x < 4 (and zero otherwise). If X < 2, toss a fair coin twice. Otherwise toss the coin once. Let N be the number of tails and let Y = X+N. Find P ( X < 2 | Y > 2.5 ).The number X is chosen at random between 0 and 1. determine the density functions of the random variables V = X/(1 - X) and W = X(1 - X)First a point is X selected at random from the interval (0,1). Then another point is selected at random from the interval (x,1) in such a way so that x+y>=1. Find the probability density function of y

A. Draw the draw of this probability density function. B. Verify that it is a probability density function of a continous random variable X. C. Find the probability that the time of a reaction more than 0.5 hour.A continuous random variable X that can assume values between x=1 and x=6 has a density function given by f(x)=15. For this density function, find F(x). Use it to evaluate P(2<X<5.9). F(x)= {____, x < ___ ; ____, ____<= x <_____ ; ____, x > ____)
- Let (X, Y ) be independent and uniformly distributed random variables (RVs) on the interval[0, 1]. Equivalently, let (X, Y ) be a point chosen uniformly at random in the unit box [0, 1] × [0, 1] on the(x, y) plane. Define the RV Z ≜ √X^2−Y^2 as the random distance of the point (X, Y ) from the origin (0, 0). Find the probability density function (PDF) for the RV Z.Let X be a continuous random variable with probability density function f(x) = 2(1-x), 0<=x <= 1. If Y = 2X - 1, find the probability density function of Y. x is lower case X is upper case. I need to get upper case of YLet X and Y be two continuous random variables with joint probability density function f(x,y) = k(x + y) for 0 < x < 1, 0 < y < 1 and 0 otherwise, where k is a constant. Find the marginal probability density functions of X and Y.
- Let X and Y be independent uniform random variables on (0, 1). Find their joint density function f (x, y). Use the joint density function to calculate the probability P(X < Y).The joint density function of the random variables X and Y is given by f(x, y) = x + y for 0 ≤ x, y ≤ 1 and f(x, y) = 0 otherwise. Consider the circle centered at the origin and passing through the point (X, Y). What is the probability that the circumference of the circle is no more than 2π?The joint density of X and Y is given by f(x,y) = e-(x+y) for 0<x<∞,0<y<∞ and 0 otherwise Find the density function of the random variable Z=X/Y.
