Suppose that you have a hat that contains slips of paper. Each slip of paper has a single number from 1-5 written on it. There are as many slips of paper with a given number as the square of that number, so 16 slips with the number 4, 9 slips with the number 3, and so on. A person is selected to draw a number at random from the hat. Let the random variable X = the number drawn from the hat. Find the mean and the variance of X
