You know relative frequency andtheoretical probability.
Written Assignment:
You are to write a report and show all your calculation for full credit. Then you will upload your report. Write neatly and work in sequential order. Please answer the following questions in order:
Experiment
- Count out 40 mixed-color M&Ms which is approximately one small bag's worth. Record the number of each colour in Table 1 .
- Use the quantity information from this Table 1 to complete the theoretical probabilities in Table 2 .
- Next, put the M&Ms in a cup.
- The experiment is to pick two M&Ms, one at a time. Donot look at them as you pick them.
- The first time through, replace the first M&M before picking the second one. Record the results in the "With Replacement" column of Table 3 . Do this 24 times.
- The second time through, after picking the first M&M, donot replace it before picking the second one. Then, pick the second one. Record the results in the "Without Replacement" column section of Table 3 . After you record the pick, putboth M&Ms back. Do this a total of 24 times, also.
- Use the experimental data from Table 3 to calculate the empirical (experimental) probability questions in Table 4.
Record all probabilities as fractions and decimals.

|---|---|
| Yellow (Y) | |
| Green (G) | |
| Blue (BL) | |
| Brown (B) | |
| Orange (O) | |
| Red (R) |

| P(R1 AND G2) | ||
| P(G2|R1) | ||

| P(doubles) | ||
| P(no doubles) |
NOTE
G2 = green on second pick; R1 = red on first pick; B1 = brown on first pick; B2 = brown on second pick; doubles = both picks are the same colour.

Discussion Questions
- Why are the "With Replacement" and "Without Replacement" probabilities different?
- Compare P(no yellows) for both Theoretical "With Replacement" and for Empirical "With Replacement". Are the decimal values "close"? Did you expect them to be closer together or farther apart? Why?
- If you increased the number of times you picked two M&Ms to 240 times, why would empirical probability values change?
- Would this change (from part 3) cause the empirical probabilities and theoretical probabilities to be closer together or farther apart? How do you know?
- Explain the differences in what P(G1 AND R2) and P(R1|G2) represent. Hint: Think about the sample space for each probability.
