Katie plays a game where she can score 1, 2, 3, 4 or 5. The random variable S S\,S represents Katie's score. She believes that S S\,S can be modelled by a uniform distribution.
The probability distribution for S S\,S is given by
| sss | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| P(S=s)P(S=s)P(S=s) | 0.2 | 0.2 | 0.2 | 0.2 | 0.2 |
Show that S S\,S can be modelled by a uniform distribution.
