Good evening,

I wrote another question for you a few posts back.

I whited it our because it is a little different from the others.

Maybe you would like to look at it.  I shall unwhite it for you.

It is the one about the bracelet. :)

Bill is 33, Frank is older than Bill. Frank's freind Bob is 3 years younger than Frank. How old is Frank?  

Frank could be any age over 33.  You have not given enough information to solve this one. :)

Yep that is why !

Oh OK   :))

Thanks Chris.

This reminds me of a story that I read to my granddaughters.

It is called

"The Bear Detectives and their Hound Dog Snuff" 

It is a good story, I shall read it to you sometime    LOL

Try question 5 :)

Well 5*6 is 30 and that is what you were expecting so YES you got them all ant it was not really that hard either was it?

Here is one that is just a little different.

Suzie has 10 different coloured beads.  She uses these beads to make a bracelet.

This bracelet does not have a clasp so there is really no beginning or end (but there is clockwise and anticlockwise)

How many different permutations of beads are possible ?

$$sin0 \ne cos0$$

There is not really a quick way exactly - you need to be methodical.

I would make a list of the 4 without Dora first (olders to youngest)    That is only  4!/(2!2!) = 6

then I woud repeatedly cut and paste that list putting Dora in each posible position. 

so for the fist cut an paste Dora can be eldest.

for the next cut and past Dora can be second and so one.

So there will be 5 cut and  pastes

5*6=30

so that would be pretty quick.   Do you understand what I mean?

Have you had enough yet or so you want another?  (I will let you finish this one first anyway)
