Hi, I'm beginner. How can I write a function like this http://upload.wikimedia.org/math/a/1/0/a106cd0b29209b7d38cd6aa9a7e5b577.png, and then make a plot? Thank you.

Did you not recieve a Mathcad 15 free with your purchase of Prime?

I looked everywhere but found nothing. Can you convert this file to Prime 3.0 version? I can't convert 'cause it asks Mathcad 15 version which I don't have. Thanks again.

    Are you sure this is a valid CDF, as your subject suggests? The appropriate density function would be zero over the whole range with two Dirac's at 0 and 1!?? Is x really a continous random variable or is a rather a coín flip? So it seems to be a discrete CDF where X can only take the values 0 and 1, right?

    Concerning the arrows take a look if the attached helps any.

      Wow, that's almost exactly was I was looking for. Seems like Mathcad has a lot hidden goods! An example I gave was actually random from wikipedia, mine function is more decent.
