A schedule has 4 meetings on Monday: Finance, Marketing, HR, and Legal. Finance cannot be first. Marketing is before HR. Legal is not last. How many valid orderings are there?

✓ Correct Answer: Option C

Total permutations with Marketing before HR: 4!/2 = 12. Remove Finance first: those with Marketing<HR and Finance=1st → 3!=6/2=3. So 12-3=9. Remove Legal last: among 9, Legal=last arrangements. Some overlap. Careful enumeration: 5 valid orderings.
