What is Implied Probability?
Implied Probability is how frequently a wager should win on ordinary to break even over the long haul. When betting at even money, if we win half our stakes and loses half our stakes we’d web even. Hence the implied probability at money is 50%. In case a bookie was giving us 2-to-1 and we lose twice and triumph after we are even. Therefore at 2-to-1 the suggested odds is 33.33 percent. This really is the most important concept in sports gambling. All wagers, regardless of what the odds format, have an implied probability. A wise player calculates the chances a team is going to win (actual probability), then examines the suggested probability offered by the bookmaker. If the implied probability the bookmaker is offering is significantly less than his calculated actual probability he bets, if not he does not bet.

In this case the return on a win is $150 (your $100 stake + $50 win), and the implied probability is $100 Stake / $150 Yield = 66.66%.
