Roulette betting questions from a newbie

[Burkans]

I just recently discovered roulette, so I have few questions about the betting on it.

1. What are the payouts for numbers 1 and 17 in Orphelins bet?

2. What is the real profit you get from those payouts?

3. What means total payout odds 6.2 to 1 in case with neighbours bet? It means I will win x6.2 from every $1 bet or something else?

4. Why with Finales a Cheval 6/9 bet we don’t bet a Straight Up bet on 36?

5. What are the real payouts for Finale en Plein 8 and Finale en Plein 6 bets? Are those 32:1 and 31:1?

6. How much profit I can get from Finales a Cheval on 7,10 payout?

7. What is the smallest number of chips I will need for the complete bet?

8. I play a multiplier game where I get â,¬135 once in 20 spins

Every other spins brings me â,¬7 losses

I need â,¬140 to hit a multiplier that will bring me â,¬135

What is the MINIMUM bankroll I'll need for a 200 spin session?

9. Can someone explain me the progression behind this strategy (James Bond)?

Spin 1: £20 wagered in total (as shown higher up)

•   Â£14 on 19 â€" 36. Win = £28 minus £20 wagered = win of £8
•   Â£5 on the Line bet. Win = £30 minus £20 wagered = win of £10
•   Â£1 on 0. Win = £36 minus £20 wagered = win of £16

Spin 2: £49 wagered, plus the £20 wagered on Spin 1, resulting in a total of £69

•   Â£35 on 19 â€" 36. Win = £70 minus £69 wagered = win of £1
•   Â£12 on the Line bet. Win = £72 minus £69 wagered = win of £3
•   Â£2 on 0. Win = £72 minus £69 wagered = win of £3

Spin 3: £162 wagered, plus £49 from Spin 2 and £20 from Spin 1, resulting in a total of £231

•   Â£116 on 19 â€" 36. Win = £232 minus £231 wagered = win of £1
•   Â£39 on Line bet. Win = £234 minus £231 wagered = win of £3
•   Â£7 on 0. Win = £252 minus £231 wagered = win of £21

Why we wager £49 on Spin 2 and £162 on Spin 3?
