Part A: A random variable is a numerical value determined by the outcome of an experiment. Briefly describe a discrete random variable. For each of the following indicate whether the random variable is discrete, and provide your reasoning.
A random variable is a quantity whose values are random and to which a probability distribution is assigned. Any situation whose outcome is uncertain is called an experiment. The value of random variable is based on the outcome of the experiment.
A discrete random variable can take finite number of possible values.
i) The distance between Gainesville, Florida, and all Florida cities with population at least 50,000
The distance, measured in miles can take infinite number of possible values and ...
