Add and subtract mixed time units

Add and subtract mixed time units

What you'll learn

  • Apply the fundamental counting principle to determine the total number of possible outcomes for compound events involving two or more independent events, with at least 80% accuracy on a summative assessment.
  • Calculate the number of possible outcomes for compound events involving permutations and combinations, differentiating between scenarios where order matters and where it does not, and justifying the choice of method in written explanations with 100% accuracy.
  • Solve real-world problems involving compound events, such as calculating the probability of specific outcomes in games of chance or surveys, and expressing the answer as a fraction, decimal, or percentage, with at least 75% accuracy on assigned problem sets.
  • Explain the difference between independent and dependent events and how this distinction affects the calculation of possible outcomes in compound events, providing clear examples and justifications during class discussions and on a short quiz, achieving a score of at least 8/10.
