View Full Version : Odds question

Can someone give me a hand on something
A tipster is W1 L10 his last 11 bets at odds of 1.91 or 10/11
What's the chance of only winning 1 from 11 bets if each game is 10/11 and how would I work it out on future
Any chance someone could explain the maths in a basic format please

Odds of 1.91 implies line bets, which are intended to have a 50% chance of winning, which is the equivalent to a coin toss.

Using an online coin toss calculator at http://www.wolframalpha.com/widgets/view.jsp?id=d821210668c6cc5a02db1069cc52464f the chance of getting heads 1 time out of 11 is 0.00537109.
