    Binomial distribution problem




    I'm having trouble setting up this problem. Any help would be appreciated. Here's the question:

    If the number of defective items selected at random from a parts inventory is considered to follow a binomial distribution with n=50 and p= .1, what is the expected number of defective parts?

    The expected value is synonymous with the mean. So, how do you calculate the mean of the binomial?
