Add and subtract fractions with unlike denominators in recipes

What you'll learn

  • Identify discrete random variables and their corresponding sample spaces from given scenarios with 80% accuracy.
  • Calculate the probability of each outcome in a discrete sample space, ensuring that the sum of all probabilities equals 1, in at least 4 out of 5 constructed probability distributions.
  • Construct a discrete probability distribution, presented as a table or graph, from a given set of data or a description of a random experiment, with all probabilities correctly represented in at least 3 out of 4 attempts.
  • Explain the properties of a discrete probability distribution, including the range of probabilities and the sum of probabilities, using precise mathematical terminology in a written paragraph of at least 5 sentences.
