Students carrying out an experiment to demonstrate a random process, such as radioactive decay, used a large number of dice to represent unstable atoms. The dice were tossed repeatedly, with those showing six discarded after each throw.
Their results are shown in Table 1.
| Throw | Dice Discarded | Dice Remaining |
|---|---|---|
| 0 | 0 | 80 |
| 1 | 12 | 68 |
| 2 | 11 | 57 |
| 3 | 6 | 51 |
| 4 | 44 | |
