1 # Mixed Random Variable 2 3 Prob L8 4 5 **Definition:** A mixed random variable is a [RandomVariables](RandomVariables.md) comprised of some continuous and discrete randomness. 6 7 An example is a random variable where there is a 1/2 chance of flipping a coin (discrete) to get 1 dollar and a 1/2 chance of getting a random number of dollars between 0 and 1 (continuous). This is a tree where the first split is between coin flip and random value then there is another layer where you flip the coin or get the random amount of money. 8 9 These types of variables can often be combined into a [CumulativeDensityFunction](CumulativeDensityFunction.md) to show the probability of getting a value or less than it.
