Friends much time I bet and I lost it. How we calculate on bet that it will be profit or loss? Any suggestion guys will help.

Betting calculation always depend on proposition bet. This is my personal experience. Once I had bet $4.93 on a three-team parlay, laying odds of 7 to 5 on the first team, and taking odds of 9 to 5 and 6 to 5 on the other two teams. (Remember, when you lay odds of 6 to 5, you are betting $6 to win $5, or some multiple of these figures. When you take odds of 6 to 5, you are betting $5 to win $6, of some multiple.) The proposition bet was that if the bookie could figure the correct payoff price of the parlay to the first two decimal places, I would pay him that amount. If he failed he would pay me the correct sum. And he paid me also.

I must say that your luck is not with you my friend. One of my friends is playing casino games and he too bet on games and win lots of time.
