Answer:
2000 players will complete the game with a perfect score.
Step-by-step explanation:
The testing phase tells us that
is the probability that a person will finish with a perfect score.
This means 1 out of 500 people will be able to finish with perfect score.
Now,
the game is given to 1,000,000 (1 million) people and how much do we expect to finish with perfect score?? Simple! It would be
the of 1 million!
We do the calculation shown below:

So, 2000 players will complete the game with a perfect score.
1 file -> 12 sheets
Now for 3 files -> 3*12 = 36 sheets, it takes up 2/3 of the total
So the total number of sheets: 36 / (2/3) = 54
The total of the running backs' salaries need to be added together first. So, $1 000 000 + $850 000 + $750 000 + $500 000 = $3 100 000. Now we divide the total number of salaries by the running back salaries: $3 100 000/$33 000 000 = 0.094 x 100 = 9.4 %.
Round off to nearest percent = 9.00 %.
