The spirit of the question is really just "Would you take 42k or a 50/50 chance at 142k"
He put it in sports betting context because it is a sports betting website but that obviously opens up the question to answers like hedging, selling equity in the bet, etc
Unless you are in need a cash infusion then the 50/50 chance is better for most people.
A better question would be something like "Would you take 500k or a 50% chance at 2 million?" then the answers would vary more based on preference, lifestyle, goals etc
