Question

1. The random variable X has the following CDF (cumulative distribution function) F_X(x) = P(X <= x) = { 0, x < 3, 0.4, 3 <= x < 5, 0.6, 5 <= x < 7, 1, x >= 7. } Draw the probability density function (PDF) of the random variable X.

          1. The random variable X has the following CDF (cumulative distribution function)
F_X(x) = P(X <= x) = 
{
0, x < 3,
0.4, 3 <= x < 5,
0.6, 5 <= x < 7,
1, x >= 7.
}
Draw the probability density function (PDF) of the random variable X.

1. The random variable X has the following CDF (cumulative distribution function)
FX(x) = P(X <= x) =

0, x < 3,
0.4, 3 <= x < 5,
0.6, 5 <= x < 7,
1, x >= 7.
