About your grandparent's house: i seems to me like once you specify the probability of renting and selling at 40% and 15%, you have already decided that the probability of neither happening would be 1-(1-.4)(1-.15)=49%. This appears inconsistent with the 45% prediction, or am I missing something?

He's assuming he won't rent it and then sell it, so the three possibilities (renting, selling, and neither) are mutually exclusive, and they do sum up to 100% as they should.
