# CMC - Problem 7

Problem 7. (3 points) The IPhOO has an ongoing Facebook competition where anyone at any time can answer with a chance to win points. A correct answer to a problem gets the full number of points the problem offers. The first 6 problems were worth the following number of points each:

1. 1 point
2. 3 points
3. 4 points
4. 7 points
5. 9 points
6. 3 points (note that this is an inaccurate statistic in real life, but assume it to be true for this problem)

Assuming people are indistinguishable, how many different possible outcomes are there? Note that an outcome is a set of people each having a positive number of points.

Is having a score of zero not included?

Every problem was solved. If you didn't solve any, then you're not included in the results.

I mean in the problem... in the contest, is it possible for a person to have a score of zero?

- 4 years, 5 months ago

That's what I was talking about. Every problem was solved in the IPhOO Facebook contest was solved. If you didn't solve any IPhOO Facebook contest problems, then you're not included in the results.

See that each person must have a positive number of points.

The correct answer was 98. Whoever posts their solution will get the full 3 points.

If you also include the different questions answered as part of the calculation , then you should mention that in the question.

All I understood from the question was that only the final marks is to be considered irrespective of whether one can get that by answering two questions or get the same by answering one ...
