- Homework Statement
- In ice hockey, you have five outfielders on the field. How many percent more outfielders does the opposing team have if you get a player sent off?
- Relevant Equations
- I interpret it this way: we have two groups, team A and team B. Both have 5 players, team A loses a 1. How many percent more do B players have than A?
The solution in my book:
5/4 = 1.25. That is 25 % more.
What I came up with:
I thought that now we have totally 9 players. So A: 4/9 and B: 5/9. The difference is 1/9 which is about 11%!
A friend told me :
The difference between B & A is 5-4=1
The changing rate is (5-4)/5 = 0.2 !
So B has 20 % more than A.
Now it's confusing. How should I interpret such a statistical question ?! I get three different answers
