The probability of getting the correct order in the spelling bee is 1 chance in 362,880.
This is a permutation problem. Our goals is to find the total number of ways that the 9 students can be ordered.
For the first spot there are 9 choices, then 8 choices, then 7 choices....
We need to evaluate:
9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 362,880
Another way to write this is: 9!
For the new expectation, 3 drivers and 2 vans are needed.
To determine, for the new expectation, how many drivers and vans do you need, the following calculation must be performed:
- 8500 x 1.5 = 12750
- 5000 x 3 = 15000
Therefore, for the new expectation, 3 drivers and 2 vans are needed.
