For the density function f x 2x/9
WebA certain continuous random variable has a probability density function (PDF) given by: f (x) = C x (1-x)^2, f (x) = C x(1 −x)2, where x x can be any number in the real interval [0,1] [0,1]. Compute C C using the normalization condition on PDFs. It should be noted that the probability density function of a continuous random variable need not ...

Web5. You make an early mistake. F Y ( y) = Pr ( Y ≤ y) = Pr ( 2 X + 1 ≤ y) = Pr ( X ≤ 1 2 ( y − 1)) = ∫ 1 1 2 ( y − 1) f X ( u) d u. Keep in mind that the bounds for X are: 1 ≤ x < ∞. So the bounds for Y will be: 3 ≤ y < ∞. WebLet X be a continuous random variable whose probability density function is: f ( x) = 3 x 2, 0 < x < 1 First, note again that f ( x) ≠ P ( X = x). For example, f ( 0.9) = 3 ( 0.9) 2 = 2.43, which is clearly not a probability! In …
