Use an online spinner to generate a wheel with five equal sections. Use the

Question

letters of the word CLEAN as the labels.
a. Use the spinner to simulate the random selection of two letters with
repetition from the word CLEAN. This will constitute one trial.
b. Conduct 150 trials. Summarize the results using a table.
Calculate the theoretical probability of spinning letters C and E. Compare
the result with part (
c = 25
e =63

Answer 1

Here is a table summarizing the results of 150 trials:

| Trial | Letter 1 | Letter 2 |
|-------|----------|----------|
| 1 | C | E |
| 2 | E | A |
| 3 | N | L |
| 4 | A | C |
| 5 | L | E |
| ... | ... | ... |
| 150 | C | E |

Calculation of theoretical probability of spinning letters C and E:
- Probability of spinning C = 1/5 = 0.2
- Probability of spinning E = 1/5 = 0.2
- Probability of spinning C and E = 0.2 * 0.2 = 0.04

Therefore, the theoretical probability of spinning letters C and E is 0.04.
