Question: In chapter 3, we learned about means and standard deviations. In section 6.1, we learned that probability distributions also can have a mean and standard deviation. Discuss what is meant by the expected value and standard deviation of a binomial distribution. How does this relate back to the material we learned in chapter 3 (averages and variations) and section 6.1(introduction to random variables and probability distributions, continuous random variable, discrete random variable and probability distribution)?
