Answer:
<em>The probability that 10 or more students will live in campus housing is approximately 0.111%</em>
Step-by-step explanation:
<u>Binomial distribution formula:</u>
<em>If the probability of success is 
, then the probability of 
successes out of 
trials will be: 
</em>
26% of college students live in campus housing. So here, 
A random sample of 15 college students is selected. So, 
Now, "10 or more students" means 10 or 11 or 12 or 13 or 14 or 15 students. That means, 
Thus, the probability that 10 or more students will live in campus housing will be........

Answer:
5.5 liters
Step-by-step explanation:
1 milliliter equals to 1/1000 part of a liter, which is 0.001 liter.
1 milliliter = 1 * 0.001 liter
So if you have 5500 milliliters that means it equals to 5500 times one milliliters and 1 milliliter = 1 * 0.001 liter, so for 5500 milliliters it is 5500 times as much
5500 * 0.001
5500 * 1/1000
5500 / 1000
5.5 liters
As long as you know this number 0.001 , then it is easily to calculate between liters and milliliters.
EXTRA:
To convert from amount A which is given in a certain quantity, to another quantity, you sometimes have to multiply and in other cases you need to divide by a certain factor. The factor defines the relationship between the quantities.
Suppose you have 1000 times 1 milliliter then you can find the amount in liters by multiplying that number of milliliters times 0.001.
It is easy to see that
1000 * 1/1000
1000 / 1000
= 1 liter, but that is easy, because I choose an easy number for the amount of milliliters to convert into liters. But it works exactly the same for any amount!
