If you can’t afford the £6.50 the publishers are very generous and have actually put quite a few of the pages on-line, so it’s worth a look

Here is a Roulette Simulator. It’s just as much fun as being in a casino, but it is completely free so you are not throwing away your money! Have a few goes and see how quickly you lose your money!

Why does the bank always win? Probability shows us that the odds are stacked against the gambler.

Let me explain.  Say we place a bet of £1 on Number 24. Assuming the roulette wheel is fair, there is one chance in 37 of this happening, because there are 37 different numbers on the roulette wheel. If you win, the bank pays you 35 times your bet. So if we do this 37 times we would expect to win once. We would lose £37 in bets and win back £36, so overall we lose £1!

A similar thing happens if you bet on pair (even) or impair (odd). Zero does not count as odd or even. So the probability of getting an even number is 18/37. The probability of an odd number is also 18/37. If you win the bank pays you the same amount as your bet. So if we play 37 times, each time betting £1, we would only expect to win 18 times. We would bet £37 and win £18 x 2 =£36, losing £1 overall.

Casinos make massive profits as they are always bound to win in the long run. True, very occasionally someone strikes lucky and has a big win, but the casino knows the odds are stacked in their favour.
