Consider the following questions:
1) What is a discrete random variable?
2) What is a continuous random variable?
3) How do you make a probability model for a random variable?
4) What is the expected value of a discrete random variable? How do you calculate the expected value?
5) How do you find the standard deviation of a discrete random variable?
6) What happens to the expected value and variance when...
a) we add or subtract a constant
b) we multiply by a constant
c) we add together two independent random variables
d) we subtract two independent random variables
7) When two independent continuous random variables have Normal models, what is true about the sum or difference of the random variables?
8) Can we add standard deviations together when dealing with random variables?
