Last week: 96x3=288
This week:204x3=612
Take this week and subtract from last week
612-288=324
So he made $324 more this week
-5—->-29
-1—->-5
0—->1
1—->7

The inverse of -9n is dividing by -9.
Answer:
0.2752512
Step-by-step explanation:
The formula you are looking for is the binomial probability:
n!
P (X) = ------------ * (P)^X * (q)^n - X
(n- X)! X!
For your particular problem:
n=7
X=2
q = 1-p = .8
7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512
Hope this helps, have a nice day/night! :D
