Probability and Statistics
Focus: Statistical Analysis of Graphs and Problem Situations


The student will determine the probability of independent and dependent events with and without replacement. 
Essential Knowledge and Skills 
  • Determine the probability of no more than three independent events.
  • Determine the probability of no more than two dependent events without replacement.
  • Compare the outcomes of events with and without replacement.
Essential Understandings
  • How are the probabilities of dependent and independent events similar? Different? If events are dependent then the second event is considered only if the first event has already occurred. If events are independent, then the second event occurs regardless of whether or not the first occurs.

Explore Learning
  1. Compound Independent Events: Compare the theoretical and experimental probabilities of compound independent events by drawing colored marbles from a bag. Record the results of successive draws with replacement of marbles to calculate the experimental probability.
  2. Compound Independent and Dependent Events: Compare the theoretical and experimental probabilities of drawing colored marbles from a bag. Record results of successive draws to find the experimental probability. Perform the drawings with replacement of the marbles to study independent events, or without replacement to explore dependent events.
  3. Spin the Big Wheel! (Probability): Step right up! Spin the big wheel! Each spin can result in no prize, a small prize, or a big prize. The wheel can be spun by 1, 10, or 100 players. Results are recorded on a frequency table or a circle graph. You can also design your own wheel and a sign that describes the probabilities for your wheel.
