There’s value in knowing the betting lines in predicting any form of competition—be it in sports or entertainment contests. For the 2013 version of Big Brother Australia, most sportsbooks have declared that Tim is the slight favourite to win this season.

Of course, nothing is final until the fat lady sings— or in case of this dispute, until the final votes have been tallied.

With the betting lines and odds come the implied probabilities or percentages on the chances of each of the remaining housemates in being named the ultimate winner of the 2013 Big Brother Australia.

Odds to Win 2013 Big Brother Australia
 Tim 1.85
Tahan 2.4
Jade 4.5

For those new to entertainment betting, below is the explanation on how these number works and how it relates to the potential payouts:

The simple formula is X (Amount of Bet) x Odds (1.85, 2.4, 4.5).

This means that for every $100 bet on Tim, the bettor will receive a payout of $185, which includes the $100 wager and the $85 win.

The odds and payouts increase as the list moves from the “favourites” to the “underdogs”. Betting $100 on Tahan will net the bettor of a total payout of $240 (or a $140 win) and Jade gets the most value among the three as a $100 bet will earn her supporters of a $450 payout (or $350 win)!

Implied Probabilities to Win 2013 Big Brother Australia
Tim 50%
Tahan 35%
Jade 15%

Will Tim, the 29-year-old student from Sydney, prove why he is pegged as the sportsbooks' favourite and be the ultimate winner? Or will the 22-year-old model Jade, a 4.5-to-1 underdog, pull-off the upset? Tahan’s 35 per cent chance looks attractive too.

Before placing those bets, check their profiles at the official Big Brother Australia site: Tahan, Jade and Tim. Voting for the winner is still open too, so bettors can still push for their picks!

It’s D-Day for the final three contenders of Big Brother Australia 2013 and the final episode starts airing at 7:30 pm (AEST) on Channel 9 or fans can follow the latest videos at the official site.
