Answer:
The expected value of X is and the variance of X is
The expected value of Y is and the variance of Y is
Step-by-step explanation:
(a) Let X be a discrete random variable with set of possible values D and probability mass function p(x). The expected value, denoted by E(X) or , is
The probability mass function of X is given by
Since the bus driver is equally likely to drive any of the 4 buses, the probability mass function of Y is given by
The expected value of X is
The expected value of Y is
(b) Let X have probability mass function p(x) and expected value E(X). Then the variance of X, denoted by V(X), is
The variance of X is
The variance of Y is
