There are 7 red marbles,5 green marbles,and 6 blue marbles is a jar.What is the minimum number of marbles to choose,without replacement,to guarantee that there is one of each color marble.
It is possible to get all 7 red marbles,then all 6 blue marbles,and then a green marble.You must choose a minimum of 7+6+1=14 marbles to guarantee that you have one of each color marble.
一个瓶子里有7块红宝石,5块绿宝石和6块蓝宝石.假设从瓶子里取出后不放回,当最少取出多少个宝石时,才能保证每种颜色各有一块?
最极端的一种可能是你先取出了7块红宝石,之后又取出了6块蓝宝石,之后才取出了绿宝石,所以你最少应该取7+6+1=14块宝石,才能保证你每种颜色各有了一块.
