I guess its a permutation cauz it says exactly one person receives A. So order matter

How about you at least TRY and do your own homework? Experts exchange is not a homework service, were here to HELP. Try, explain what you tried and THEN others will help you.....
</div>


<div>
Its not a homework. I try it bymyself first than ask a question for suggestion

<div>
And the most distinguishing part for the graded students: The ORDERING of the students having Grade A is not defined in any manner.

COMBINATION! (No Repetition Type)

This is certainly a permutation problem:<br />
<br />
&nbsp; &nbsp;ABBBBBB &nbsp; &nbsp;is not the same as &nbsp; BBBABBB &nbsp; or &nbsp; BBBBBBA<br />
<br />
But the answer is<b> NOT </b>going to be in the form &nbsp; P(m, n).<br />
<br />
Try to think logically, and restate the problem:<br />
<br />
How many ways are there to distribute one A among seven students?<br />
How many ways are there to distribute B's, C's, and D's to the other six?<br />
<br />
<br />

Assigning grades

The Math / Science topic primarily includes discussions of mathematics, physics, statistics and economic analysis, but also biology, chemistry and other sciences.

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.
