    1. Chapter 10 introduces us to multinomial experiments. What is the difference between a multinomial and a binomial experiment? Please give me an example.
    ? Multinomial experiment: Experiment with a fixed number of independent trials, where each outcome falls into exactly one of several categories.
    ? Binomial experiment: Experiment with a fixed number of independent trials, where each outcome falls into exactly one of two categories.
    ? Example: (I just need an example. Thanks.)

    2. The shape of the chi-square distribution looks lop-sided compared to the bell shaped curve. Why are these shaped differently? (This is what I have so far please see below. Is there anything that I am missing?)
    ? Unlike the normal and Student t distributions, the chi-square distribution is not symmetric.
    ? The values of the chi-square distribution can be 0 or positive, but they cannot be negative.
    ? The chi-square distribution is different for each number of degrees of freedom.
