Here is a short test to show how much you know or don't know about gambling.

Answer TRUE or FALSE for the Questions 1 to 9 and write down your answer for Question 10.


Q1. The longer you go without a win, the more likely you will win the next round. For example, the longer you roll two dice without getting double six, the more likely it is to come up the next roll.


Q2. When playing the Lotto or Toto, the numbers 3, 19, 21, 30, 34, 48 are more likely to come up than the numbers 1,2,3,4,5,and 6.

Q3. A sure-win system at the casino is to double-or-quit i.e. doubling your stakes until you win and then quitting.

Q4. Someone must win the lottery, so if I play, I will eventually win.

Q5. In a contest between a university-trained mathematician and a street-smart poker whiz with nerves of steel, the mathematician will always win because he knows the odds.

Q6. According to Stanford University mathematician Persi Diaconis, it takes seven shuffles to randomise an ordered peck of cards because strangely, giving it more than seven shuffles can reintroduce the order that was there originally.

Q7. In a Lotto draw, any combination of six numbers has the same likelihood of being the winning combination as any other and so there is nothing you can do to improve your likelihood of winning.

Q8. Lotteries go as far back as biblical times when Moses used a lottery to award parcels of land west of the Riven Jordan.

Q9. In a Lotto draw in Singapore, there are 45 numbers to choose from.  You need to match all six numbers to win the jackpot and the probability of this happening is 1 in 8,145,060 or roughly one in eight million.

Q10. In a sequence of 12 coin tosses, eleven tosses were Heads.  The professor said the odds of the next toss being a Tail is 1 in 2 or 50%.  The street-smart gambler told the professor: "You got to be kidding.  The coin is loaded.  The odds of the next throw being a Tail is only 1 in 12.  I bet it would be another Head. Would you bet Head or Tail? (Scenario adapted from The Black Swan)

Answer Key:
Q1 to Q5 are False; Q6 to Q9 are True; I will bet with the street-smart guy--the next toss is likely to be a Head.  I have seen 13 straight Reds at a Roulette table and I almost lost my pants because I was thinking like the Professor! Beside, I ran out of money using "double-or-quit".
