An unexpected result involving sums of random numbers

[Gil]

As suggedted by Barbosa, I selected the model HP48 (instead of HP49-50G) from EMU48.

With exact Barbosa's programs and the above selected model, the elapsed time is now only 11.9s.

However, to try and have better results with model HP49-HP50 from EMU48, I selected approximate mode and put a point (dot) after the digits to transform them from integers into reals. Then, the elapsed time is 12.0s, still a wee bit "worse" than HP48 (from EMU48).
