Re: April 2007 IBM Ponder This Challenge
[ QUOTE ]
with most of the hard math done by the poster jason1990. [/ QUOTE ] This is not right. f97tosc was the first to post a derivation of (7 - 3\sqrt{5})/2. That was hard math and is arguably the heart of the matter. He/she(?) also contributed in other significant ways. This thread has over 1000 views and is currently the fifth listed result in a Google search for "ibm ponder this," so we should not unfairly minimize anyone's contributions.

We can reformulate the problem to the question "what is the probability that the frog will not eventually land on 0, assuming it starts from minus infinity?". [/ QUOTE ] Hi - sorry for my dimwittedness: can you please explain more in detail (for the slow dude) how one gets to this from the original? Thanks!
