I'm going to reword your question so it's easier to answer. I'm also going to pretend no one has 3 or more accounts because it's irrelevant.
22% have no accounts (220/1000)
What is the probability that 4 or more of the 10 participants has no account?
(220/1000)*(219/999)*(218/998)*(217/997)*(10 choose 4)
There are 8 possible desired outcomes.
This would be represented as a probability of 8/31.

Answer:
70 square units
Step-by-step explanation:
The overall outline is 15 units wide and 8 units high, for an area of ...
A = WH
A = (15 units)(8 units) = 120 units²
__
The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...
A = (5 units)(10 units) = 50 units²
__
The shaded area is the difference between the overall area and the white space taken out:
shaded = 120 units² -50 units² = 70 units²
