Q1) "Investment" (zero cost) has 80% chance of paying $125 and a 20% chance of losing $375. I understand that expected payout is (.8x$125)-(.2x$375)=$25. I can make this "investment" every month. Or we can say, how much money do I need to have say 98% probability of not going broke and being able to reap expected long them expected pay-off of the $25/month".
