Example 5-10. (a) A random variable X is distributed at random between the values0 na I so that its probability density function is : f(x) = kx² (1 – x³), where k is a constant. Fina the value of k. Using this value of k, find its mean and variance . (6) A variable X is distributed at random between the values 0 and 4 and its probability density function is given by : f(x) = kx³ (4 – x)². Find the value of k, the mean and standard deviation of the distribution. %3D
