Using proportions, it is found that:
- a) The table is completed with 0.1.
- b) The team played 75 games.
What is a proportion?
A proportion is a fraction of a total amount.
Item a:
The sum of the frequencies is of 1, hence, the table is completed with 1 - (0.55 + 0.35) = 0.1.
Item b:
Considering that there were n games, we have that:
- The team won 0.55n games.
- The team lost 0.35n games.
The difference was of 15, hence:
0.55n - 0.35n = 15
0.2n = 15
n = 15/0.2
n = 75
The team played 75 games.
