Does anybody know how to show part a) without just using math to show that the two sides are equal (which we have to do for b).  I'm stuck on how to go about this.

If anyone wants to work on this as a group, I'm willing. I'm struggling some and have class during his office hours. Call/text 317-605-6720. thanks.

5.3 - 20, 22, 24, 32 | 5.4 - 21, 22, 28, 31, 38

I thought it would be nice to have a template for this week's homework so it would be easier to access information about the problems.

I like the template idea. This will be helpful!

Section 5.3

20. Does anyone know how to account for overcount in these problems? Or do you not have to take that into account

a) I'm struggling to get this one. It's not just 3 0's and pick the rest, it's exactly 3 0's. How would that effect the Permutation (or combination)?

Look at example 14 in section 5.3.


22.




24. I keep getting a small number for 24, but I know the answer should be larger. Can anyone help me?

Think about how we distinguished how many of each fruit we stole using dividers. Perhaps you need to take into account the permutations of the men and women.



32. Any ideas on 32 b?

do we use the form (n!)/(n-r)!*r! on this portion or is it just n!/r! ?




Section 5.4

21. Does anybody know how to show part a) without just using math to show that the two sides are equal (which we have to do for b). I'm stuck on how to go about this.
