- 1What is a Random Variable?A mapping from each outcome to a real number
- 2What is Pr(Y = 2) ?1/2
- 3What is E(Y)?7/2
- 4According to Linearity of Expectation, what is this expression equal to?
- 5What is an Indicator Random Variable?A random variable that can only be a 0 or 1. It has the property: E(I) = Pr(I = 1), where I is the indicator random variable.
