Q4, chapter 5, page 232, Introduction to probability, Blitzstein. Please solve this question:Let X be a continuous r.v. with CDF F and PDF f.Find the conditional CDF of X given X > a (where a is a constant with P (X > a) ? 0). That is, find P (X ? x|X >a) for all a, in terms of F.(b) Find the conditional PDF of X given X >a (this is the derivative of the conditionalCDF).(c) Check that the conditional PDF from (b) is a valid PDF, by showing directly thatit is nonnegative and integrates to 1.
