Question

Please ignore the section discussing the 3 diagrams.

Tree Diagrams and Probability A box contains 4 red and 8 blue balls. Three balls are drawn from the box. Print the 3 different tree diagrams. 1. Complete the symbolic tree diagram by placing appropriate symbols on the branches and at the ends of the branches as indicated 2. Assuming the balls are drawn without replacement, complete the WO R diagram by placing appropriate probabilities on the branches and at the ends of the branches as indicated. 3. Assuming the balls are drawn with replacement, complete the W R diagram by placing appropriate probabilities on the branches and at the ends of the branches as indicated. Assume the balls are drawn without replacement. Use the WOR diagram to find these probabilities. 1. P(all 3 balls are the same color) 2. P(all 3 balls are blue) 3. P(there is at least one ball of each color) 4. P(there are 2 red balls and 1 blue ball) 5. P(3B) 6. P(2R) Assuming the balls are drawn with replacement, use the W R diagram to answer the same 6 questions. Note: 2R means the second ball is red.
