WebX could be one. X could be two. X could be equal to two. X could be equal to three. X could be equal to three. So these are the possible values for X. And now we're just going to plot the probability. The probability that X has a value of zero is 1/8. That's, I'll make a little bit of a bar right over here that goes up to 1/8. So let draw it ... WebNov 27, 2014 · 16. Consider the random variable X with probability density function. f ( x) = { 3 x 2; if, 0 < x < 1 0; otherwise. Find the probability density function of Y = X 2. This is the first question of this type I have encountered, I have started by noting that since 0 < x < 1, we have that 0 < x 2 < 1. So X 2 is distributed over ( 0, 1).

WebIn order to find the mean and variance of X, we first derive the mgf: MX(t) = E[etX] = et ( 0) (1 − p) + et ( 1) p = 1 − p + etp. Now we differentiate MX(t) with respect to t: M ′ X(t) = d dt[1 − p + etp] = etp M ″ X(t) = d dt[etp] = etp Next we evaluate the derivatives at t = 0 to find the first and second moments: M ′ X(0) = M ″ X(0) = e0p = p.
