原理：随机数随机1,10000个数，其中随机到到数和10000*0.1（概率）=1000进行比较，随机数大于1000则不选中，反之则选中。

local successCount =0;

local commitPercent = 0.1;

local percent = commitPercent*10000;

for i=1,100 do

local randomNum = math.random(1,10000);

sysLog(“–randomNum–“..randomNum..”–commitPercent–“..percent)

if randomNum>percent then

sysLog(“–false–“)

else

sysLog(“–true–“)

successCount = successCount +1;

end

end

sysLog(“–successCount–“..successCount)
