If I take 1k to play 2-5 nl being a total of 200big blinds (2 bullets). And expect to win 2k 40 percent of my sessions and bust 1k the other 60 percent. How would if figure out if this is plus ev ? . In other words how would I figure the answer to this in a formula. Also what would be the minimum amount of sessions I have to win to break even thanks. Would be great if you guys show me how to solve it step by step (main focus here is to learn how to figure it out.)
