Question 1174742
.
<pre>

Jobs are different and women are different,



                    T H E R E F O R E 


    +-------------------------------------------------------+
    |   in this problem the order of arranging DOES MATTER. |
    +-------------------------------------------------------+



THEREFORE, the answer is  7*6*5*4*3 = 2520 ways.


It is the product of 5 consecutive integer numbers in descending order starting from 7.


First job vacancy can be filled by any of 7 ladies,             giving 7 options.


Second job vacancy can be filled by any of remaining 6 ladies,  giving 6 options


     .  .   .   and so on to the last, 5-th vacancy inclusive.


It gives the formula.


All these arrangements are DIFFERENT.

Solved, answered and explained.  And completed.


Do not accept any other answer.

How @ewatrrr interprets, &nbsp;solves and answers this problem, &nbsp;is &nbsp;INCORRECT.


Since the order is &nbsp;IMPORTANT, &nbsp;this problem is on &nbsp;PERMUTATIONS.


It is &nbsp;NOT &nbsp;on &nbsp;COMBINATIONS.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;****************************************************************

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is the &nbsp;MAJOR &nbsp;POINT &nbsp;in the solution of this problem 

    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to recognize to which type it does really belong.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;****************************************************************



@ewatrrr teaches you &nbsp;INCORRECTLY &nbsp;in this major point.


She does it incorrectly &nbsp;EVERY &nbsp;DAY, &nbsp;because she &nbsp;DOES &nbsp;NOT &nbsp;know the subject.
