Sheng Di jewellery lottery
The probability of the first person winning the prize is111. No matter how noisy, his probability will not change.

The probability of the second person drawing is also (10/1) * (110) =1.

The probability of the third person winning is 0. Suppose he is here, taking a black ball from the box, and the probability of not winning the prize is 1.

The probability of the fourth person being drawn is (10/1) * (9/10) *1* (1/8) = 9/88 > 8/88.

So the first person really lost.
