Question 1161126
<br>
It's best to use only standard keyboard characters when posting your questions.  Other characters may make your post difficult or impossible to read.<br>
Another tutor answered this question -- possible from you, or possibly from another student -- and got the same answer you got.<br>
You say the answer you and she got is not right....  Do you know what the answer is supposed to be?<br>
For me, at least, it is aggravatingly easy to come up with a method to solve a combinatorics/probability problem that seems valid but is not.  If you have the right answer and post it with your problem, it might help some tutor to guide you to that answer.<br>
