Answer: 0.0325
Step-by-step explanation:
Binomial probability distribution formula for x successes in n trials:-
, where n is the number of trials , p is the probability of success.
Given : The probability that taxpayers who filed their tax return are electronically self-prepared their taxes : 
If three tax returns submitted electronically are randomly selected, then the probability that all three were self-prepared is given by :-

Hence, the probability that all three were self-prepared =0.0325
Answer: B
Step-by-step explanation:
First, simplify the main expression. The answer is 21.
Then simplify A. It is -106. That is not equal to 21 so A is wrong.
Then simplify B. That is 21. That means B is correct and you don’t have to solve C or D.
