If X is uniformly distributed over (−1, 1), find (a) P{|X| > 1/2}; (b) the density function of the random variable |X|. The density function of X is given by If E[X] = 3/5, find a and b. If X has hazard rate function λX(t), compute the hazard rate function of aX where a is a positive constant. Let X have probability density fX. Find the probability density function of the random variable Y defined by Y = aX + b. Suppose that n points are independently chosen at random on the circumference of a circle, and we want the probability that they all lie in some semicircle. That is, we want the probability that there is a line passing ...Post your question
