Usually, Freebitco users play the multiply BTC game on 2× multiplier. Where the win chance is 47.5%.
Right. That would be even worse.
I got the first one. But how have you calculated these two probabilities here?
The probability of having 20 consecutive loses = (0.51)
20 = 0.0000014171
The probability of not having 20 consecutive loses and winning = 0.9999985829
The probablity of winning winning 100,000 times without having 20 consecutive loses = (0.9999985829)
100,000 = 0.8679
The probablity of winning winning 1,000,000 times without having 20 consecutive loses = (0.9999985829)
1,000,000 = 0.2424
