Did I Correctly Complete the Tree Diagram?

Click For Summary
SUMMARY

The forum discussion centers on the completion of a tree diagram related to probability calculations. The user confirmed that the probability in the rightmost column, specifically the third entry from the top, should be calculated as 11/12 multiplied by 1/12, resulting in 11/144. This calculation was identified as a typo correction, affirming that the rest of the tree diagram appears accurate. The final answer for part (b) is indeed 11/144.

PREREQUISITES
  • Understanding of probability theory
  • Familiarity with tree diagrams
  • Basic arithmetic operations
  • Knowledge of fractions and their simplification
NEXT STEPS
  • Study tree diagram construction techniques
  • Learn advanced probability concepts, such as conditional probability
  • Explore common probability distribution types
  • Practice solving probability problems using tree diagrams
USEFUL FOR

Students in statistics, educators teaching probability, and anyone involved in mathematical problem-solving using tree diagrams.

well first want to see if i completed the tree diagram correctly
text in the boxes are mine.

In the rightmost column of probabilities, third from the top, you want 11/12 X 1/12 = 11/144. I can tell this is only a typo. Otherwise looks good.

Yep typo, so is the answer for (b) just 11/144
