  1. Discrete and continuous random variables - Khan Academy

    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. …

  2. Random variables | Statistics and probability - Khan Academy

    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 …

  3. Random variables and probability distributions | Khan Academy

    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 …

    Basic idea and definitions of random variables

  5. Random variables (video) | Khan Academy

    Random variables are really ways to map outcomes of random processes to numbers. So if you have a random process, like you're flipping a coin or you're rolling dice or you are measuring the rain that …

  8. Probability with discrete random variables - Khan Academy

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

  9. Probability density functions (video) | Khan Academy

    You have discrete, so finite meaning you can't have an infinite number of values for a discrete random variable. And then we have the continuous, which can take on an infinite number.
