3) A uniformly distributed continuous random variable, X, is described by the PDF shown. It is input into asystem producing a new random variable Y, described by the equation shown. Determine an expressionfor the CDF for Y as a function of fx(x). You do not need to solve non-trivial integrals. Just set them up.-2fx(x)1/42 xy= g(x)= |x|

A gasoline station gets its supply once a week. Suppose the PDF of X = demand in thousands of gallons for gasoline is: fx(x) = 5(1 – x)*I(0.1)(x) a. What is the probability that the demand for gasoline in a given week is more than 500 gallons? b. How much gasoline must the station get from its supplier in order for the probability that its supply will be exhausted in a given week shall be 0.01?
A fair coin is tossed three times and the random variable x equals the total number of heads. Find the sketch F(x) and f(x).
Suppose that n observations are chosen at random from a continuous pdf fY(y). What is the probability that the last observation recorded will be the smallest number in the sample? I asked this question earlier today, but didn't quite understand all of the response. P(y1<=yn)p(y2<=yn) and so on was used, but shouldn't the yn be listed first in the inequality since we want to know if yn is the smallest?
Suppose X is a random variable, whose pdf is defined as follows: 2x = (²x) (u(x) - u(x − 3)) where u(x) is the unit step function. Determine the conditional pdf fx(x 1
