This document contains a statistics worksheet with questions about random variables and probability.
The first section asks to classify 5 random variables as discrete or continuous. The second section provides 4 experiments and asks to identify the random variable and possible values for each.
The third section describes an experiment where 5 cars are shipped, 2 with blemishes. It asks to list the 8 elements of the sample space using letters for blemished and non-blemished, and assign a value of X, the random variable for number of blemished cars purchased, to each sample point.
