Answer:
Step-by-step explanation:
there are 40320 possible arrangements. that would be 8!
the probability of picking the correct order randomly would be 1 / 40320 = .0000248015873.
in order words, the probability of picking the correct order on a random basis, such as picking the names out of a hat, is not very good.
<u>for example:
</u>
suppose there were only 3 reamining candidate.
3! = 3*2 = 6
there would be 6 possible arrangements. if the candidates were abc, then the 6 possible arrangements would be:
abc
abc
bac
bca
cab
cba
for 4 candidates, multiply 6 * 4 = 24
then 5 * 24 = 120
then 6*120 = 720
then 7*720 = 5040
then 8 * 5040 = 40320
1 / 6 is manageable.
1 / 24 less.
1 / 8 becomes pretty impossible.
Answer:
X^2/3
Step-by-step explanation:
Answer:
(x + 5)
Step-by-step explanation:
(x² - 25) ÷ (x-5)
=(x² - 5²) ÷ (x-5)
Using the formula a² - b² = (a + b)(a - b) you get
= (x + 5)(x - 5) ÷ (x - 5)
With division you can cut both (x - 5)
So the answer is (x + 5)
