Question 1185669
.
<pre>

As it is worded, printed, posted and presented, this problem is INCOMPLETE.


To be complete, it MUST say that among 4 possible answers to each question ONLY ONE ANSWER is correct.


If we accept this assumption / (axiom),  then the  <U>ANSWER</U>  is  {{{C[15]^2}}} = {{{(15*14)/2}}} = 15*7 = 105.
</pre>Solved.


-------------


But if we do not accept that axiom/assumption, then the answer can be different.
