There is a big bag with many balls in it. Each ball has a number written on it. Among them, there are 10 balls with 0, 11 balls with 1, 12 balls with 2...19 balls with 9. If the ball is taken from the bag with eyes closed, at least how many balls must be taken out to ensure that there must be 4 balls in the taken out balls. The numbers written on these 4 balls just form 2007.
有一个大口袋，里面装着许多球，每个球上都写着一个数字，其中写0的有10个，写1的有11个，写2的有12个…写9的有19个．如果闭着眼睛从袋中取球，那么至少要取出多少球，才能保证取出的球中必有4个球，这4个球上面所写的数字恰好组成2007．
