I'm interested in the risk profile of members here. Please answer honestly as if it was a real situation and you had to make a decision right now. Biased coin flip, result either heads or tails. Heads you win, tails you lose. Stake to play is $1,000. Payout is even money, i.e. if you win, you get $2,000 back for your $1,000 stake. The bias is that heads results 2/3 of the time. You only get 1 attempt, will you play? Secondary question not part of the poll. If you could increase your stake, still limited to 1 attempt, how much would you be willing to risk in real dollars for this positive outcome expectation random event?
