You are thinking about funding a Kickstarter campaign for a hybrid mechanical/digital calendar for which you're willing to pay $$\$ 125$$. To receive a calendar, the company required that you pledge $$\$ 100$$. You think there's about an $80 \%$ chance of the company succeeding, but if the product fails, you will not receive a refund. Is this a fair bet? Would you pledge the $$$ 100$$ ? Hint: Use your consumer surplus if the company succeeds to evaluate the bet.
