As defined in the website mathinsight.org, a random variable is a variable that is subject to random variations so that it can take on multiple different values, each with an associated probability. Random variables can be discrete or continuous. An example of a discrete random variable would be the result of rolling a six-sided die. A random variable X modeling the result of such an experiment would take on a value from the set {1,2,3,4,5,6}, each value with probability 1 6 . On the other hand, an example of continuous random variable would be the result of randomly choosing a number between 0 and 1. A random variable X modeling the result of such an experiment could take on any real number in the interval [0,1], where each number would be equally likely. As example for random variables I can use the discrete random variable resultant from the experiment of me receiving mail. The variable will take one of 2 possible values, these being {received mail, did not received mail}. The random variable x modeling the result of this experiment will take on randomly one

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
