Answer:

Step-by-step explanation:
This is just 2 part:
1. Raise "10" to the 4th power
2. Subtract expression of #1 from "f"
So,
we have f
and we have 10^4
Now we subtract 10^4 from f, thus we have:

That's simply it.
47.607 - 35.957 = 11.65
11.65 gallons of paint is left
Answer: 31.25%
Two ways to solve this problem:
#1: Use the formula: 
#2 Use a graphing calculator and use the function binompdf(n, p, x)
#1: Formula:

#2: Faster method
binompdf(6, 0.5, 3) = 0.3125
