here's the probability question: lets say you place a trade which has a 50/50 chance of being favorable. if it is unfavorable you lose $100. if it is favorable, you have 60% chance of making $100, 20% chance of making $240, and a 20% chance of losing $30 (commissions). should you place the trade, and what is your probability of each level of profit or loss? since there are four possible outcomes, what are the chances of each? thanks in advance.
