Step-by-step explanation:
If we have n trials, each with m possible outcomes, the total number of possible outcomes is:
In this question:
6 games(trials), so .
Each with three possible outcomes, so
Then:
There are 729 possible results are there for the series
Answer:
the correct choice is marked
Step-by-step explanation:
Let x represent the smaller number. Then the larger number is 8x, and the difference is ...
8x -x = 280
7x = 280 . . . . . simplify
x = 40 . . . . . . divide by 7
The larger number is 8x = 8(40) = 320.

<em>Additional comment</em>
Effectively, we have solved for the multiplier (40) that gives the ratio with 320 on top and a difference between top and bottom of 280:
