Saved a checkpoint:
Split the first part, about basketball, into a separate question.
Added random names.
Changed the randomisation of the probabilities so that everyone is pulled from the same distribution (apart from the missing person, who accumulates the error when the probablities for the others are rounded off)

Changed the storm to an electrical fault, so it's more plausibly instantaneous.
Improved some of the wording in the advice.
