title: matlab code on geometric random variable
body: <p>I am asked to Write a code to generate a geometric RV with p=0.25 and use it to calculate the probability that the RV takes a value greater than or equal to 4. Basically, I am not aware of matlab but I tried using help in matlab. And I came to know that I should use geornd function. Can anyone help me how to use the function and how I should enter the parameters to get the required results?</p>
