Is the winning rate of cf crossing the firewire lottery high?

For me, a RMB player ... the lottery is a thing of the past, and the probability of winning the first three lottery games is 50%. After the first three times, the probability of winning business cards and coupons is 70%, so the lucky draw can only be drawn for the first three times ... As for the time of the lucky draw, there is no saying ... 8 yuan has the highest probability of winning, with 5 yuan pistol for 30 days and machine gun for 7 days. But it's basically a pistol .. I once spent 200 RMB to smoke cigarettes in 8 yuan and 5 yuan respectively. The probability of a pistol in 8 yuan is 60%, and the probability of a machine gun is 50%. Finally, I give you personal advice: it is better to buy a lottery ticket than a gun, but you must buy a gun for half a year or 1 year, or you will lose money. This is personal advice, I hope it will help you ... thank you!
