Given the arithmetic sequence an = 2 − 3(n − 1), what is the domain for n? a all integers where n ≤ 1 b all integers where n ≥ 1 c all integers where n ≥ 0 d all integers

all integers where n is greater than or equal to 1

a) The odds that such a taxpayer will be audited is 4%.

b) The odds against such a taxpayer being audited is 96%.

Step-by-step explanation:

a) Data and Calculations:

The probability of an IRS audit = 3.8% for U.S. taxpayers who file form 1040 and earned $100,000.

This is the same as the odds that such a taxpayer will be audited.  Odds is the likelihood or chance that an event will take place.

b) The probability of not being audited is 100 - 3.8% = 96.2%

The odd against being audited is the likelihood or chance that an event will not take place.
