Suppose that we toss a fair coin and, then toss a fair four-sided die. "Fair- ness" means that the coin/die is equally likely to land on each its possible sides. (a) Define the sample space for this experiment. (b) Let X be the random variable defined as (number of heads) + (die score modulus 2)". Identify the possible values that X can have, and write down the event X = z for each value of z. Then calculate the probability mass function for X. (c) Calculate the expectation and variance of X.
