Consider a very simple weekly lottery: A number between one and one million (inclusive) is randomly chosen each week.

1. If you play one number this week, what are your odds of winning?
2. If you won this week, what are the odds of you winning by choosing the same number next week?
3. If you won this week, what are the odds of you winning by choosing a different number next week?
4. What are the odds of the winning number being 50, two weeks in a row?
5. What are the odds of the winning number being the same, two weeks in a row?
