1. ## marbles

a bag contains 3 red, 4 white, and 5 blue marbles. Jason begins removing marbles from the bag at random, one at a time. What is the least number of marbles he must remove to be sure that he has at least 1 marble of each color?

I thank you all in advance,
thank you

Worse case scenario is keeps taking the most common colours and none of the rarest leading to selecting 4 white and 5 blue.

Plus 1 red to get one of each colour

3, if he draws one color after another, he only needs to draw 3 marbles

Least number to be sure of at least one of each colour. If 3 are taken then
they could all be red, or whatever without there being one of each colour.

The first answer in this thread is correct.
