Question 1120189
.
<pre>
We have notes of three different nominations and coins of four different nominations.


In all, there are notes and coins of  3 + 4 = 7  different nominations.


Each of them may go with the coefficient 1 or 0.


Hence, in all, we have  {{{2^7}}} = 128  different opportunities (including one empty = zero opportunity).

<U>My response</U>.  &nbsp;&nbsp;It is because I admitted the empty case, &nbsp;which corresponds to the zero value.


If to exclude it, &nbsp;you will get exactly &nbsp;127&nbsp; opportunities.
