2. Suppose the probability of an IRS audit is 1.7 percent for U.S. taxpayers who file form 1040 and who earned $100,000 or more. 1.7% = 0.017 What are the odds that such a taxpayer will be audited? (Round your answers to the nearest whole number.) GIVEN: ODDS ARE 1 to 58 PLEASE USE FORMULA : P(A)/(1-P(A)) P(A)= 0.017

We have P(audited) = 0.052, which gives us P(not audited) = 1 - P(audited) = 1 - 0.052 = 0.948.

3. Find the following permutations nPr. Please use formula =n!/(n-r)! In Excel use the formula =FACT(number) to get a factorial value for n! and (n-r)! Find nPr for when: n = 8 r = 3

4. Using the same method above, find nPr for when: Find nPr for when: n = 8 r = 5 5. Using the same method above, find nPr for when: Find nPr for when: n = 8 r = 1
