summer math puzzles

*********************

1) Suppose we wish to arrange 5 people {a, b, c, d, e}, standing side by side, for a portrait. How many such distinct portraits (“permutations”) are possible?
2) {a, b, c, d, e} arranging 5 objects, in such a way that “a” is always first. How many different orders count as being distinct.
3) Now suppose we start with the same 5 people {a, b, c, d, e}, but we wish to make portraits of only k = 3 of them at a time. How many such distinct portraits are possible?
4) Finally suppose that instead of portraits (“permutations”), we wish to form committees (“combinations”) of 3 people from the original 5. How many such distinct committees are possible?
5) Suppose we wish to arrange 5 people {a, b, c, d, e} around a circular table. How many such table arrangements are possible? 

I have blogged a few puzzles
that are appropriate for 6th grade on up.

When you go to the blog,
you may want to avoid looking at the answers

until you have given yourself
(or your kids) a chance to try them.

Have fun!
