- If the probability density of X is given by f(x) =kx3(1 + 2x)6 for x > 00 elsewhere where k is an appropriate constant, find the probabilitydensity of the random variable Y = 2X 1 + 2X . Identify thedistribution of Y, and thus determine the value of k.Mr. Guo determines that a random variable of interest X follows a uniform distribution on the interval (4, 12). Answer each of the following questions: (a) Find the density function of X. (b) Compute P(5 ≤ X ≤ 7). (c) Compute P(6 ≤ X ≤ 10).Let X denote the reaction time, in seconds, to a certain stimulus and Y denote the temperature (◦F) at which a certain reaction starts to take place. Suppose that two random variables X and Y have the joint density

Draw a graph of the density function, and then use it to help find the following probabilities: A. P (X > 28) = B. P(X < 11.5) = C. P(9 < X < 26) = D.
