    Using rbinom and pbinom

    We just started learning R in my statistics class, and I am confused by the use of the rbinom and pbinom functions. Here is the type of problem I am trying to do. Suppose we roll a die 50 times. The random variable Y=the number of rolls that show a 5 or a 6. How would I find: P(Y>=30)...

    Comparing probability distributions over discrete random variables

    Hi guys Sorry if the post is not in the right place but I am new here. I am comparing the performance of two monte carlo methods. The results I got are the marginals for the same set of random variables. Lets say for example: First Method Second Method X1 0.62...
