Discrete Probability Distributions: Learn It 2

  • Create a discrete probability distribution and use it to find probabilities
  • Determine if probability models meet the conditions for a discrete probability model

Properties of Discrete Probability Distributions

There are a few important properties of discrete probability distributions that we should consider:

  • The values associated with the random variable of interest are numerical and discrete.
  • All possible values of the random variable are listed in a table or graph, with each value having an associated probability greater than or equal to [latex]0[/latex] and less than or equal to [latex]1[/latex].
  • The sum of all probabilities in the table or graph equals [latex]1[/latex].
