What is the probability

I played a roulette game recently. I put money on 30 numbers including the 0. I stop at 10 spins and this is what came up:
numbers left out: 1 4 5 11 12 31 34 (7 numbers out of 37)
The numbers of 10 spins are as followed from first to last: 4 5 1 18 33 24 34 34 35 12.
Is this fair or not?

are we to guess that this was an online roulette game and not in a real casino?



The probability of winning 4 times or less in 10 spins is 0.004767773 or about 1 in 210

Of course a 156 unit loss (same bets) is never fun that fast.



Even the first 3 in a row losing is only about 1 in 148



So I say it looks fair (but sucks)
