In his pocket, a boy has 3 red marbles, 5 blue marbles, and 5 green marbles. How many will he have to take out of his pocket to ensure that he has taken out at least one of each color? Choose the correct choice from the following options.
A) 9 B) 10 C) 11 D) 12 E) 13
The worst case scenario would be that he has taken 5 blue and 5 green, a total of 10 marbles, and still doesn't have 3 distinct colors. But the next draw, marble number 11, will surely be red as only the red marbles are left in his pocket.   The answer is 11.
