I have a 6 sided die with the numbers 1, 2, 3, 3, 4, 5 on it. I also have a hat filled with numbers. When I pick a number out of the hat, I get a number between 1 and 10. The hat number has a mean of 2 and a standard deviation of 2.5. I make a new random variable by combining these two previous random variables. The new random variable is made by taking the number I...
