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 :-

Answer:
the top one, (-1,3)
Step-by-step explanation:
They have some of the same numbers
(16^3 + 16x^2 + 19x + 12) / (4x + 3). Start by factoring the numerator.
(4x + 3) (4x^2 + x + 4) / (4x + 3). Since (4x + 3) is a term in both the numerator and the denominator, we can cancel them out.
You're left with: 4x^2 + x + 4.
Money must serve as a medium of exchange, a storehouse of value and a unit of account
Answer: Option B, D, and E
<u>Step-by-step explanation:</u>
Money, the term coined in terms of the following three services.
