Assuming that the reading of these colored flag messages is done from left to right (or top to bottom), depending on the way displayed, then 10P4 is the correct answer. Do you know how to compute that permutation value?

I suggest that you read up on Permutations and Combinations--in a textbook, or online via Wikipedia or Khan Academy or the like.
In general, nPr = n! divided by (n-r)! where the exclamation mark means "factorial."
The answer in this particular problem is the product of the four numbers 10, 9, 8 and 7.

Thank you,
we just started working with this on Monday and this is from my assignment. I have been away from school for 40 years and am excited to get back into the learning of new subjects, but this is pretty deep for me. After you explained your answer I was able to work it on the calculator.
I appreciate your help. We have very limited time with tutors and class moves fast for this almost 60 year old Nana!!
