  Hi,

  The statement below creates an array of arrays and *not* the 
  NormalDistribution objects. 

  >           Probs= new NormalDistribution[11][94];

  All references in Probs array are null and improper use will cause a 
  NullPointerException.

  In order to initialize the array you have to create the objects like 
  this:

    NormalDistribution[][] Probs;
    Probs = new NormalDistribution[11][94];
    for(int i = 0; i < 11; ++i) {
      for(int j = 0; j < 94; ++j) {
        Probs[i][j] = new NormalDistribution();
      }
    }
