Random variables can be any outcomes from some chance process, like how many heads will occur in a series of 20 flips of a coin. We calculate probabilities of random variables and calculate expected …

A random variable is some outcome from a chance process, like how many heads will occur in a series of 20 flips, or how many seconds it took someone to read this sentence. Calculate probabilities and …

A random variable can take on many, many, many, many, many, many different values with different probabilities. And it makes much more sense to talk about the probability of a random variable …

Discrete random variables can only take on a finite number of values. For example, the outcome of rolling a die is a discrete random variable, as it can only land on one of six possible numbers. …

An introduction to a special class of random variables called binomial random variables

Practice calculating probabilities in the distribution of a discrete random variable.

Define a random variable for a quantity of interest by assigning a numerical value to each event in a sample space; graph the corresponding probability distribution using the same graphical displays as …
