What to Focus On

  • Probability measures the likelihood of an event occurring
  • Range: 0 ≤ P(E) ≤ 1
  • 0 represents impossible events, 1 represents certain events

  • Random Experiment: Unpredictable outcome activity
  • Sample Space (S): All possible outcomes
  • Event (E): Desired outcomes subset

  • Mutually Exclusive: Cannot occur together
  • Independent: One doesn't affect the other
  • Dependent: One affects the other's probability

Common Mistakes to Avoid

When using AND in probability, you should add the individual probabilities instead of multiplying them

The probability of an event can be greater than 1

P(A or B) always equals P(A) + P(B)
