I have a theoretic question on my probability class. Suppose that you know the X random variable. Can you calculate the cumulative distribution function? If not, why not?

Can you find out what the cumulative distribution function is if you know the random variable X?

If you know the distribution of X, the cumulative is the integral of its density function. So yes, I can.
If you have drawins from X, you may be able to fit a distribution, so that you get an estimated continuous density function. You may not be able to express the integral in terms of elementary functions (e.g. the cumulative of a normal distribution), but you may have a numerical approximation. So yes, I can.
