There are 6 pockets all together.  You checked two of them and it wasn't 
there.  So you can forget about those 2, and now there are 4 pockets left.
The total number of ways for your next try is 4.
The number that will be successful is 1.
The probability of success on the next one is  <em>1/4  =  25% .</em> 
=======================================================
Another method of solution, somewhat more complex:
Total number of pockets = 6.
Amount of money missing = $10
First partial sum, i.e. sum of numbers 
 in the first part of the problem = 6 + 10  =  16.
Total number of pockets  =  6
Current value of cargo pants on a fashion scale from 1 to 10  =  -2.
Second partial sum =  6 - 2  =  4. 
  Probability = (second partial sum) / (first partial sum) = 4/16  =  <em>25% </em>.
