Answer:

Step-by-step explanation:
For this case we want to find this probability:

Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:

The other possibility is use the normal standard table and we got a similar result. 
 
        
             
        
        
        
To find how much each person will get, you have to divide the amount available by the people. There are 2 ways I believe we can do this.
First way
Let's divide.
2÷9= 2/9
Each person would get 2/9 of a gallon if they shared it.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Second way
I believe it would be easier to convert this into cups. There are 16 cups per gallon.
16×2= 32
Let's divide that by 9.
32÷9= 3 5/9 cups per person.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Each person would receive 2/9 of a gallon.
        
             
        
        
        
33.3% is the answer, I think
20/60 ---> 1/3, covert this to a percentage and it equals 33.3%

Answer:
48
Step-by-step explanation:
The exterior of the crate is 10 inches long, meaning that the inside measurement is 8 inches.  Next, the 8 inch width corresponds to 6 inches inside.  Finally, the 3 inch height corresponds to 1 inch interior height.
Thus the inside floor of the box is 8 by 6 inches, or 48 square inches.
Since the inside height is only 1 inch, this means that 48 one-inch cubical blocks will fit inside the crate.
