Okay so here are my answers to your questions :)

Combo: 10

Perm: 1/34650 (I got 1/ 39,916,800 first time round)

Working for perm

total combinations 11P11 with any arrangement

For just Mississippi:

---------- (I hope that’s 11 spaces)


1 for first box
4 for second (4 possible I’s)
4 for third (4 possible S’s)
3 for fourth (3 possible S’s)
3 for fifth (3 possible I’s)
2 for 6th box (2 S’s remaining)
1 for 7th box (1 s remains)
2 for 8th box
2 for 9th (2 P’s)
1 for 10th
1 for 11th

Let me know if this was the right working

Cheers

Thanks Dr Steve for the lucid explanation. I will add it to my combination and permutation notes. I think I have the hang of it now though! The notion of ordering is still a little fuzzy though :)
